Although the health benefits of exercise and exposure to nature are well established, most evidence their interaction comes from acute observations single sessions activity. However, documenting improved outcomes requires ongoing interventions, measurement multiple outcomes, longitudinal analyses. We conducted a pilot study guide development protocol for future studies that would assess physiological psychological outcomes. Herein, we report measured thirty-eight participants before after...
There are urgent calls for the transformation of agriculture and food systems to address human planetary health issues. Nutrition-sensitive agroecology promise interconnected solutions these challenges, but evidence their impact has been limited.
Abstract Connections between food security and nutrition (FSN) mental health have been analytically investigated, but conclusions are difficult to draw given the breadth of literature. Furthermore, there is little guidance for continued research. We searched three databases analytical studies linking FSN health. Out 30,896 records, we characterized mapped 1945 onto an interactive Evidence Gap Map (EGM). In these studies, anthropometry (especially BMI) diets were most linked (predominantly...
BackgroundBolstering farm-level crop diversity is one strategy to strengthen food system resilience and achieve global security. Women who live in rural areas play an essential role production; therefore, we aimed assess the associations between women's empowerment diversity.MethodsIn this secondary analysis of cross-sectional data, used data from four cluster-randomised controlled trials done Burkina Faso, India, Malawi, Tanzania. We assessed using indicators Women's Empowerment Agriculture...
Abstract Water security requires not only sufficient availability of and access to safe acceptable quality for domestic uses, but also fair distribution within across populations. However, a key research gap remains in understanding water inequality its dynamics, which turn creates an impediment tracking progress towards sustainable development. Therefore, we analyse the using data from 7603 households 28 sites 22 low- middle-income countries, measured Household Insecurity Experiences Scale....
Abstract Household survey data from 27 sites in 22 countries were collected 2017–2018 order to construct and validate a cross-cultural household-level water insecurity scale. The resultant Water Insecurity Experiences (HWISE) scale presents useful tool for monitoring evaluating interventions as complement traditional metrics used by the development community. It can also help track progress toward achievement of Sustainable Development Goal 6 ‘clean sanitation all’. We present HWISE scores...
In 2015, depressive disorders led to over 50 million disability-adjusted life years lost globally, with more than 80% occurring in low- and middle-income countries. Depressive are also risk factors of a number adverse maternal child health outcomes. To our knowledge, the Singida Nutrition Agroecology Project (SNAP-Tz), is first nutrition-sensitive agriculture (NSA) intervention identified improve women's probable depression (2020). Food security has been posited play an important role...
Background: Food insecurity (FI) is common globally and can have lifelong consequences. However, few studies longitudinally examined how FI varies across gestation the postpartum period (“the first 1000 days”); none explored this in sub-Saharan Africa or context of HIV. Objective: To assess prevalence covariates days among Kenyan women. Methods: All pregnant women attending 7 clinics western Kenya (n = 1247) were screened for HIV (Individual Insecurity Access Scale) between September 2014...
There is growing recognition of the importance maternal mental health for well‐being both mothers and children. In addition to being public concern on its own right, depression could impede women's capacity provide quality care their However, covariates depression, especially in low‐resource settings, are not well‐understood. particular, role gender equity needs further investigation. Therefore, we sought understand associated with a rural farming community Tanzania. We hypothesized that...
High prevalence of stunting in Singida, Tanzania has been attributed to sub‐optimal infant and young child feeding (IYCF) practices. To evaluate the appropriateness a proposed participatory agroecological nutrition peer education intervention for improving IYCF growth, we described assessed covariates suboptimal A cross‐sectional survey was conducted with mothers fathers households children <2 years (n=322). Multivariate logistic regression used analyze exclusive breastfeeding (EBF) <6...
Production diversity and women's empowerment are two ways by which nutrition-sensitive agriculture interventions thought to improve children's diet, but, few empirical studies have tested these pathways. We therefore investigated the impact of Singida Nutrition Agroecology Project (SNAP-Tz; NCT02761876) on child's dietary diversity, as well mediating role production that relationship. SNAP-Tz is a randomized trial participatory agroecology nutrition intervention mentor farmers lead their...
Antiretroviral (ARV) adherence is a strong predictor of improved health outcomes and treatment effectiveness among persons living with HIV. Food insecurity low social support are have been demonstrated to predict reported nonadherence pregnant women, but the relationship has not evaluated using an objective indicator adherence. Therefore, we explored impacts food on ARV drug concentrations in hair postpartum Kenyan women Hair samples were collected from 83 HIV + subset observational...
Nutrition-sensitive agricultural interventions are theorized to improve child's diet through asset provision and program participation. Although some programs measure participation, predictors of participation understudied. We therefore investigated men's women's in Singida Nutrition Agroecology Project (SNAP-Tz; NCT02761876). In SNAP-Tz, 'mentor farmers' led their peers (smallholder farmers with children < 1 year at baseline) learning about agroecology, nutrition, gender equity meetings...
Abstract Objective: To investigate if food security mediated the impact of a nutrition-sensitive agroecology intervention on women’s depressive symptoms. Design: We used annual longitudinal data (four time points) from cluster-randomised effectiveness trial participatory intervention, Singida Nutrition and Agroecology Project. Structural equation modelling estimation total, natural direct indirect effects was to security’s role in intervention’s risk probable depression (Center for...
There has been no survey of nutrition status among primary school children in Guinea‐Bissau. To fill this gap, a USDA funded pilot project and Cluster Randomized Control Trial to improve the population were conducted. We assessed weight‐for‐age, height‐for‐age, BMI‐for‐age Z‐scores (WAZ, HAZ, BAZ) anemia 4,807 children. 
 Nutrition is concern (23.8% WAZ <‐2, 6.9% <‐3, 16.0% HAZ 3.8% 15.7% BAZ 3.5% 18% mild anemia, 21.6% moderate 5.5% severe anemia). Boys scored worse than girls on...
Participation is key to the successful implementation of nutrition-related interventions, but it has been relatively overlooked.We sought describe participation intensity among smallholder farmers in a randomized nutrition-sensitive agroecology study rural Tanzania. We explored association between baseline characteristics and overall (quantitatively at individual level qualitatively group level), with 2 process indicators, outcomes.Data came from 7 rounds surveys 295 women 267 men across 29...
Farm production diversity has long thought to be a primary driver of dietary diversity. Few studies have explored the drivers among women, who are often vulnerable sub-optimal diets. We therefore investigated how affects women's in smallholder farming communities rural Tanzania. Specifically, we hypothesized that women households with greater farm would higher Female farmers (n = 462) were surveyed on agricultural practices 2018 and their diet subsequent harvest season as part Singida...
Nutrition-sensitive interventions often fail because they lack contextual awareness. Participatory dissemination (PD), the formal sharing of research data with participants, can improve impact by fostering coproduction knowledge and increasing participant involvement in project. Here, we demonstrate how PD revealed previously unidentified challenges solutions to dietary diversity, strengthened a nutrition-sensitive project Tanzania. Singida Nutrition Agroecology Project (SNAP-Tz) is...
