(2017-Oct-17) Greenland, Katie; Chipungu, Jenala; Chilekwa, Joyce; Chilengi, Roma; Curtis, Val
BACKGROUND: Diarrhoea is a leading cause of child death in Zambia. As elsewhere, the disease burden could be greatly reduced through caregiver uptake of existing prevention and treatment strategies. We recently reported the results of the Komboni Housewives intervention which tested a novel strategy employing motives including affiliation and disgust to improve caregiver practice of four diarrhoea control behaviours: exclusive breastfeeding; handwashing with soap; and correct preparation and use of oral rehydration salts (ORS) and zinc. The intervention was delivered via community events (women's forums and road shows), at health clinics (group session) and via radio. A cluster randomised trial revealed that the intervention resulted in a small improvement in exclusive breastfeeding practices, but was only associated with small changes in the other behaviours in areas with greater intervention exposure. This paper reports the findings of the process evaluation that was conducted alongside the trial to investigate how factors associated with intervention delivery and receipt influenced caregiver uptake of the target behaviours. METHODS: Process data were collected from the eight peri-urban and rural intervention areas throughout the six-month implementation period and in all 16 clusters 4-6 weeks afterwards. Intervention implementation (fidelity, reach, dose delivered and recruitment strategies) and receipt (participant engagement and responses, and mediators) were explored through review of intervention activity logs, unannounced observation of intervention events, semi-structured interviews, focus groups with implementers and intervention recipients, and household surveys. Evaluation methods and analyses were guided by the intervention's theory of change and the evaluation framework of Linnan and Steckler. RESULTS: Intervention reach was lower than intended: 39% of the surveyed population reported attending one or more face-to-face intervention event, of whom only 11% attended two or more intervention events. The intervention was not equally feasible to deliver in all settings: fewer events took place in remote rural areas, and the intervention did not adequately penetrate communities in several peri-urban sites where the population density was high, the population was slightly higher socio-economic status, recruitment was challenging, and numerous alternative sources of entertainment existed. Adaptations made by the implementers affected the fidelity of implementation of messages for all target behaviours. Incorrect messages were consequently recalled by intervention recipients. Participants were most receptive to the novel disgust and skills-based interactive demonstrations targeting exclusive breastfeeding and ORS preparation respectively. However, initial disgust elicitation was not followed by a change in associated psychological mediators, and social norms were not measurably changed. CONCLUSIONS: The lack of measured behaviour change was likely due to issues with both the intervention's content and its delivery. Achieving high reach and intensity in community interventions delivered in diverse settings is challenging. Achieving high fidelity is also challenging when multiple behaviours are targeted for change. Further work using improved tools is needed to explore the use of subconscious motives in behaviour change interventions. To better uncover how and why interventions achieve their measured effects, process evaluations of complex interventions should develop and employ frameworks for investigation and interpretation that are structured around the intervention's theory of change and the local context. TRIAL REGISTRATION: The study was registered as part of the larger trial on 5 March 2014 with ClinicalTrials.gov: NCT02081521 .
Efficacy of the Common Elements Treatment Approach (CETA) for Unhealthy Alcohol Use Among Adults with HIV in Zambia: Results from a Pilot Randomized Controlled Trial.
(2022-Feb) Kane, Jeremy C.; Sharma, Anjali; Murray, Laura K.; Chander, Geetanjali; Kanguya, Tukiya; Skavenski, Stephanie; Chitambi, Chipo; Lasater, Molly E.; Paul, Ravi; Cropsey, Karen; Inoue, Sachi; Bosomprah, Samuel; Danielson, Carla K.; Chipungu, Jenala; Simenda, Francis; Vinikoor, Michael J.
This randomized controlled trial tested the efficacy of a multi-session, evidence-based, lay counselor-delivered transdiagnostic therapy, the Common Elements Treatment Approach (CETA), in reducing unhealthy alcohol use and comorbidities among persons living with HIV (PLWH) in Zambia. Adult PLWH with (a) unhealthy alcohol use plus mental health or substance use comorbidities, or (b) severe unhealthy alcohol use were randomized to receive a single-session alcohol brief intervention (BI) alone or BI plus referral to CETA. Outcomes were measured at baseline and a 6-month follow-up and included Alcohol Use Disorders Identification Test (AUDIT) score (primary), depression and trauma symptoms, and other substance use (secondary). We enrolled 160 participants; 78 were randomized to BI alone and 82 to BI plus CETA. Due to COVID-19, the trial ended early before 36 participants completed. Statistically and clinically significant reductions in mean AUDIT score from baseline to 6-month follow-up were observed in both groups, however, participants assigned to BI plus CETA had significantly greater reductions compared to BI alone (- 3.2, 95% CI - 6.2 to - 0.1; Cohen's d: 0.48). The CETA effect size for AUDIT score increased in line with increasing mental health/substance use comorbidity (0 comorbidities d = 0.25; 1-2 comorbidities d = 0.36; 3+ comorbidities d = 1.6). Significant CETA treatment effects were observed for depression, trauma, and several other substances. BI plus referral to CETA was feasible and superior to BI alone for unhealthy alcohol use among adults with HIV, particularly among those with comorbidities. Findings support future effectiveness testing of CETA for HIV outcomes among PLWH with unhealthy alcohol use.Clinical Trials Number: NCT03966885.
Experiences of capacity strengthening in sanitation and hygiene research in Africa and Asia: the SHARE Research Consortium.

The Sanitation and Hygiene Applied Research for Equity (SHARE) Research Programme consortium is a programme funded by the United Kingdom Department for International Development (DFID) that aims to contribute to achieving universal access to effective, sustainable, and equitable sanitation and hygiene worldwide. The capacity development component is an important pillar for this programme and different strategies were designed and implemented during the various phases of SHARE. This paper describes and reflects on the capacity-building strategies of this large multi-country research consortium, identifying lessons learnt and proposing recommendations for future global health research programmes. In the first phase, the strategy focused on increasing the capacity of individuals and institutions from low- and middle-income countries in conducting their own research. SHARE supported six PhD students and 25 MSc students, and organised a wide range of training events for different stakeholders. SHARE peer-reviewed all proposals that researchers submitted through several rounds of funding and offered external peer-review for all the reports produced under the partner's research platforms. In the second phase, the aim was to support capacity development of a smaller number of African research institutions to move towards their independent sustainability, with a stronger focus on early and mid-career scientists within these institutions. In each institution, a Research Fellow was supported and a specific capacity development plan was jointly developed.Strategies that yielded success were learning by doing (supporting institutions and postgraduate students on sanitation and hygiene research), providing fellowships to appoint mid-career scientists to support personal and institutional development, and supporting tailored capacity-building plans. The key lessons learnt were that research capacity-building programmes need to be driven by local initiatives tailored with support from partners. We recommend that future programmes seeking to strengthen research capacity should consider targeted strategies for individuals at early, middle and later career stages and should be sensitive to other institutional operations to support both the research and management capacities.

INTRODUCTION: While in school, girls require an environment that is supportive of menstrual hygiene management (MHM) in order to ensure regular school attendance and participation. Little is known about schoolgirls access to and practice of MHM in rural Zambia. This study explores girls' experiences of MHM in rural schools of Zambia from the perspectives of schoolgirls, schoolboys and community and school-based adults key to MHM for schoolgirls. METHODS: In July and August 2015, we conducted this qualitative exploratory study in six rural schools of Mumbwa and Rufunsa districts of Zambia. Twelve in-depth interviews (IDIs) and six focus group discussions (FGDs) were conducted among girls ages 14-18 who had begun menstruating. Two FGDs with boys ages 14-18 and 25 key informant interviews were also conducted with teachers, female guardians and traditional leaders to provide the context within which schoolgirls practice MHM. RESULTS: Most girls reported learning about menstruation only at menarche and did not know the physiological basis of menstruation. They reported MHM-related challenges, including: use of non-absorbent and uncomfortable menstrual cloth and inadequate provision of sanitary materials, water, hygiene and sanitation facilities (WASH) in schools. In particular, toilets did not have soap and water or doors and locks for privacy and had a bad odor. Girls' school attendance and participation in physical activities was compromised when menstruating due to fear of teasing (especially by boys) and embarrassment from menstrual leakage. Boys said they could tell when girls were menstruating by the smell and their behaviour, for instance, moving less and isolating themselves from their peers. Girls complained of friction burns on their inner thighs during their long journey to school due to chaffing of wet non-absorbent material used to make menstrual cloth. Girls preferred to dispose used menstrual materials in pit latrines and not waste bins for fear that they could be retrieved for witchcraft against them. Though traditional leaders and female guardians played a pivotal role in teaching girls MHM, they have not resolved challenges to MHM among schoolgirls. CONCLUSION: When menstruating, schoolgirls in rural Zambia would rather stay home than be uncomfortable, inactive and embarrassed due to inadequate MHM facilities at school. A friendly and supportive MHM environment that provides education, absorbent sanitary materials and adequate WASH facilities is essential to providing equal opportunity for all girls.
One Health Baseline Study Report
(Centre for Infectious Disease Research in Zambia (CIDRZ), 2026-12-17) Somwe, Paul; Barry Walsh, Paula; Riblet, Michelle; Butler, David; Lumpa, Mwansa; Sharma, Anjali; Rios, Rafaella; Whelan, Niamh; Chipungu, Jenala; Banda, Humphrey; Mataa, Liywalii
The One Health Baseline Research Study was conducted to assess knowledge, practices, and regulatory frameworks related to food safety, animal health and disease surveillance, and the control of animal medicines in Zambia. The study aimed to inform a just transition toward a sustainable and resilient food system by strengthening One Health interventions that reduce production and consumption shocks and mitigate crisis risks. Using a mixed-methods approach, quantitative and qualitative data were collected from 340 stakeholders, including livestock and crop farmers, food processors, buyers and retailers, and regulators across six districts in Eastern, Lusaka, Northern, and Southern Provinces. Findings indicate that stakeholders possess a holistic understanding of One Health, recognising the interdependence of food safety, animal health, environmental sustainability, and socio-economic factors. Positive progress was observed, including strong awareness of zoonotic diseases among livestock farmers, high compliance with food business registration requirements, and recognition of inspectors as trusted information sources. However, significant challenges persist, particularly related to limited institutional capacity, regulatory overlaps, inadequate risk management skills, weak oversight of animal medicines, and insufficient infrastructure and training. Misuse of veterinary drugs and pesticides poses risks to public health, animal health, and the environment, contributing to antimicrobial resistance and undermining disease control efforts. The study highlights the importance of strengthened institutional coordination, improved policy communication, risk-based approaches, and inclusive stakeholder engagement from farm to fork. Digital innovations such as the Zambia Animal Health Information System demonstrate potential for enhancing disease surveillance and evidence-based decision-making. Overall, the findings underscore the need for integrated, risk-based, and community-informed One Health strategies to improve food safety, support sustainable livelihoods, and strengthen Zambia’s agri-food system resilience.

BACKGROUND: Digital health interventions show promise in improving the uptake of HIV services among adolescents and young people aged 15 to 24 years in sub-Saharan Africa. OBJECTIVE: This study aimed to pilot-test a theory-based, empirically grounded web-based application designed to increase condom-related knowledge, sexual and reproductive health (SRH) communication, and healthier choices among young Zambians. METHODS: We conducted a pre-post quasi-experimental evaluation of the user-driven Be in the Know Zambia (BITKZ) web application using web-based surveys and in-depth interviews (IDIs) on the phone. We enrolled participants using social media advertisements. Our final analysis set comprised 46.04% (749/1627) of participants in the intervention group (which received the BITKZ link) and 53.96% (878/1627) of participants in the comparison group (no intervention). We collected survey data at study enrollment (baseline) and 5 weeks after the first enrollment in each group. Approximately 85% (637/749) of BITKZ users completed a user survey, of whom 9.3% (59/637) participated in IDIs. We calculated the time interfacing with BITKZ using the application log files. We conducted descriptive analyses to describe baseline characteristics and the user experience. At the endline, we assessed association using a t test and adjusted logistic regression for binary outcomes and ordinal regression for ordered outcomes, conditioning on age, sex, marital status, and employment status. We used adjusted average treatment effects (aATE) to assess the effects of BITKZ intervention. We conducted rapid matrix analyses of IDI transcripts in Microsoft Excel, sorting the data by theme, gender, and experience rating. RESULTS: Users rated BITKZ highly (excellent: 352/609, 57.8%; good: 218/609, 35.8%). At the endline, the intervention group had a higher level of knowledge related to condoms (adjusted odds ratio [aOR]: 1.35, 95% CI 1.06-1.69) and on wearing condoms correctly (aOR: 1.23, 95% CI 1.02-1.49). Those who had full-time employment had increased odds of knowing how to wear condoms correctly (aOR: 1.67, 95% CI 1.06-2.63) compared with those who reported being unemployed, as did men when compared with women (aOR: 1.92, 95% CI 1.59-2.31). Those in the intervention group were more likely to score higher for intention to test for sexually transmitted infections (STIs; aATE 0.21; P=.01) and HIV (aATE 0.32; P=.05), as well as for resisting peer pressure (aATE 2.64; P=.02). IDIs corroborated increased knowledge on correct condom use among men and female condoms among women, awareness of STIs and testing, and resistance to peer pressure. Interviewees provided examples of more open SRH communication with partners and peers and of considering, adopting, and influencing others to adopt healthier behaviors. CONCLUSIONS: Despite the high baseline awareness of SRH among Zambian adolescents and young people with internet access, BITKZ provided modest gains in condom-related knowledge, resistance to peer pressure, and intention to test for STIs and HIV.
Recommendations for hand hygiene in community settings: a scoping review of current international guidelines.

BACKGROUND: Hand hygiene is an important measure to prevent disease transmission. OBJECTIVE: To summarise current international guideline recommendations for hand hygiene in community settings and to assess to what extent they are consistent and evidence based. ELIGIBILITY CRITERIA: We included international guidelines with one or more recommendations on hand hygiene in community settings-categorised as domestic, public or institutional-published by international organisations, in English or French, between 1 January 1990 and 15 November 2021. DATA SOURCES: To identify relevant guidelines, we searched the WHO Institutional Repository for Information Sharing Database, Google, websites of international organisations, and contacted expert organisations and individuals. CHARTING METHODS: Recommendations were mapped to four areas related to hand hygiene: (1) effective hand hygiene; (2) minimum requirements; (3) behaviour change and (4) government measures. Recommendations were assessed for consistency, concordance and whether supported by evidence. RESULTS: We identified 51 guidelines containing 923 recommendations published between 1999 and 2021 by multilateral agencies and international non-governmental organisations. Handwashing with soap is consistently recommended as the preferred method for hand hygiene across all community settings. Most guidelines specifically recommend handwashing with plain soap and running water for at least 20 s; single-use paper towels for hand drying; and alcohol-based hand rub (ABHR) as a complement or alternative to handwashing. There are inconsistent and discordant recommendations for water quality for handwashing, affordable and effective alternatives to soap and ABHR, and the design of handwashing stations. There are gaps in recommendations on soap and water quantity, behaviour change approaches and government measures required for effective hand hygiene. Less than 10% of recommendations are supported by any cited evidence. CONCLUSION: While current international guidelines consistently recommend handwashing with soap across community settings, there remain gaps in recommendations where clear evidence-based guidance might support more effective policy and investment.
The impact of the SKILLZ intervention on sexual and reproductive health empowerment among Zambian adolescent girls and young women: results of a cluster randomized controlled trial.
(2025-Jun-05) Sheira, Lila A.; Mulubwa, Chama; Chiu, Calvin; Chipungu, Jenala; Coakley, Chelsea; Smith, Helene; Upadhyay, Ushma D.; Chilambe, Chansa; Chibwe, Besa; Pry, Jake M.; Mkandawire, Boyd; Musonda, Maggie; Bolton-Moore, Carolyn ; Liu, Jenny
BACKGROUND: Zambian adolescent girls and young women (AGYW, age 15–24) experience a disproportionate burden of HIV and unintended pregnancy. Sports-based interventions, which affect sexual health behaviors via improving sexual and reproductive empowerment, may be an innovative and effective approach for promoting HIV and unintended pregnancy prevention. We sought to evaluate the impact of a peer-led, sports-based intervention on sexual and reproductive empowerment among in-school Zambian adolescent girls and young women. METHODS: Data come from the ‘SKILLZ’ study, a cluster randomized controlled trial evaluating the impact of a peer-led, sports-based health education program. Sexual and reproductive empowerment, a secondary outcome of SKILLZ, was measured via the 23-item Sexual and Reproductive Empowerment for adolescents and young adults scale (range 0–92, higher = more sexual and reproductive empowerment) three times over approximately 24 months. We conducted a difference-in-differences analysis to evaluate intervention impact over time. RESULTS: The study enrolled 2,153 AGYW (1134 intervention; 1019 control) across 46 secondary schools in Lusaka. Median age at baseline was 17; participants were largely unmarried (96%), with 20% reporting any sexual activity. By endline, nearly 40% reported being sexually active. Between baseline and midline, attending an intervention school was associated with a 6.21-point increase in overall score calculated using the imputed sample (standard error [SE]: 0.75, CONCLUSION: The intervention moderately impacted Sexual and Reproductive Empowerment scores; results were magnified among sexually active AGYW. Given adolescence is a critical period for sexuality and gender programming, as well as for sexual debut, empowerment interventions at schools may support downstream sexual health behaviors that will impact the life-course of AGYW. TRIAL REGISTRATION: This study was registered in ClinicalTrials.gov (NCT04429061) on March 17th, 2020. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12978-025-02046-6.
Theory-based formative research on oral rehydration salts and zinc use in Lusaka, Zambia.
(2016-Apr-12) Greenland, Katie; Chipungu, Jenala; Chilengi, Roma; Curtis, Valerie
BACKGROUND: A theoretically grounded formative research study was carried out to investigate behaviour related to the use of Oral Rehydration Salts (ORS) and zinc tablets. The purpose was to inform the design of the behaviour change component of the Programme for Awareness and Elimination of Diarrhoea in Lusaka Province, Zambia, which aims to reduce childhood morbidity and mortality from diarrhoeal disease. METHODS: Fourteen behaviour trials were conducted among caregivers of children under-five with diarrhoea. Caregivers were recruited from two clinics situated in rural and peri-urban Lusaka. Trials took ten days and data were captured using video, observation and repeated interviews. Additional data were collected through focus group discussions with mothers, observations in clinics and pharmacies and interviews with clinic and pharmacy staff. Findings were organised according to categories of behavioural determinants from Evo-Eco theory. RESULTS: Participants were all familiar with ORS and most knew its purpose. ORS use was motivated by symptoms of dehydration, rather than the start of a diarrhoea episode, and was stopped when the child had visibly recovered energy. Only four of 14 behaviour trial participants were observed to correctly prepare ORS. Errors were mainly associated with measurement, resulting in a solution that was too concentrated. ORS was not observed to be given to children at clinics. Although zinc was unknown in this population, it was positively received by mothers keen to learn whether zinc would work better than alternative treatments to stop diarrhoea. CONCLUSIONS: ORS was sub-optimally prepared and used at home. It was not used while waiting to be seen at a clinic. In homes, the behaviour change intervention should promote early and continued use of correctly prepared ORS. In the longer-term, these behaviours may best be encouraged by changing the product design or sachet size. Despite its unfamiliarity, this population was well disposed to the use of zinc as a treatment for diarrhoea; when zinc is new to a population, promoting zinc as a solution to stopping diarrhoea, which mothers seek, may drive initial trial. Ensuring the availability of zinc in public clinics and private pharmacies prior to commencement of any promotion activities is crucial.
Using a theory-driven creative process to design a peri-urban on-site sanitation quality improvement intervention.
(2019-May-14) Tidwell, James B.; Chipungu, Jenala; Chilengi, Roma; Curtis, Val; Aunger, Robert
BACKGROUND: Behavior change interventions have been developed by drawing from many different theories using design processes of varying specificity. We describe the development of a behavior change intervention to improve on-site peri-urban sanitation quality in Lusaka, Zambia using the Behavior Centered Design (BCD) framework to explain the results of the process applied to improving the quality of shared peri-urban sanitation and compare them to similar interventions. METHODS: We used the BCD behavioral determinants model to synthesize the data from our literature review and formative research. Then, we partnered with creative professionals using a design process to develop a theory-driven on-site peri-urban sanitation intervention. Particular attention was paid to the implications of using BCD for intervention development on improving its effectiveness, increasing the contributions to knowledge for other behaviors and settings, and advancing the discipline of applied behavioral science. RESULTS: Based on findings from a literature review and formative research, we designed an intervention to encourage landlords to improve their toilets by making them more accessible, desirable, hygienic, and sustainable. The intervention involved landlords meeting in facilitated groups every 2 weeks with individual follow-up after each meeting. The meetings presented surprising "hidden camera"-style videos to reveal tenants' perspectives, used participatory activities to help landlords reevaluate the benefits they would derive from improving sanitation on their plots, and provided practical guidance and mechanisms to facilitate the performance of construction and cleaning behaviors. CONCLUSIONS: Using the BCD framework provided an easy-to-follow intervention design process. The resulting intervention is highly creative and multi-faceted, with each element having a theoretical role in an explicit theory of change. The development of this theory-driven intervention advances applied behavioral science by facilitating evaluation of each of the behavior change techniques and the overall delivery mechanism hypothesized to change the target behaviors. This informs the adaptation of these findings to improving on-site sanitation in other settings and the iterative development of the BCD model, which can be used to more effectively change other behaviors.
WASH and learn: a scoping review of health, education and gender equity outcomes of school-based water, sanitation and hygiene in low-income and middle-income countries.
(2025-May-06) Bick, Sarah; Davies, Katherine; Mwenge, Mwamba; MacLeod, Clara; Braun, Laura; Chipungu, Jenala; Chidziwisano, Kondwani; Dreibelbis, Robert
School-age children in low-income and middle-income countries (LMICs) face health and educational challenges due to inadequate water, sanitation and hygiene (WASH) in schools (WinS). Evidence for the impact of WinS interventions is limited and inconsistent, and previous systematic reviews have faced challenges in synthesising data due to varied interventions, study designs and outcome measures, although most do not examine this variability in more detail. This scoping review identified 83 experimental studies from 33 LMICs measuring a primary or secondary health or educational outcome among pupils, published up to November 2023, using a systematic search of seven databases and searching of reference lists of previous systematic reviews and included articles. These included 65 studies (78%) not included in previous WinS reviews and encompassed 313 intervention effects across 14 outcome domains. Interventions comprised an array of WASH technologies and approaches, often combining infrastructure and behaviour change methods and frequently integrated with other school-based initiatives like deworming. 36 studies (43%) measured only behavioural or knowledge outcomes. Our comprehensive inventory of study outcomes identified 158 unique outcome measures, with 72% measured in exactly one study. Common outcomes included parasitic infections, anthropometric measures and school absence, but approaches to measurement varied widely even for similar outcomes. Only 7% of results were disaggregated by gender, limiting assessment of differential impacts. Our findings underscore the need for standardised outcome measures in WinS research incorporating a complete definition of the assessment and aggregation approach, greater attention to gender-specific impacts, and further exploration of modalities and functions of WinS interventions alongside novel meta-analysis methods to disentangle effects of diverse intervention components.
