Food security mediates the decrease in women's depressive symptoms in a participatory nutrition-sensitive agroecology...

Area of Science:

• Agricultural Science
• Nutrition Science
• Mental Health Research

Background:

• Depressive symptoms are a significant concern among women farmers.
• Nutrition-sensitive agroecology interventions aim to improve health outcomes.
• The mediating role of food security in this context requires investigation.

Purpose of the Study:

• To determine if food security mediates the impact of a nutrition-sensitive agroecology intervention on women's depressive symptoms.
• To analyze the causal pathway between agricultural interventions, food security, and mental health.
• To assess the intervention's effect on probable depression in rural women farmers.

Main Methods:

• Longitudinal data from a cluster-randomised trial in Tanzania (Singida Nutrition and Agroecology Project).
• Structural equation modelling used to estimate direct and indirect effects.
• Participants: 548 food-insecure, married, smallholder women farmers with young children.

Main Results:

• The intervention reduced the odds of probable depression by 43% (OR=0.57).
• Changes in food insecurity explained approximately 10% of the intervention's effect on depression.
• Baseline depression prevalence was around 32% in both control and intervention groups.

Conclusions:

• This study provides the first evidence that improved food security positively impacts women's mental health by reducing depressive symptoms.
• Nutrition-sensitive agricultural interventions offer broader benefits, including mental health improvements, with food security playing a crucial causal role.
• Participatory nutrition-sensitive agroecology interventions show potential for enhancing women's well-being in farming communities.
