Resumen

Background: The extent to and mechanisms by which agricultural biodiversity may influence diet diversity and quality among women are not well understood. Objectives: We aimed to 1) determine the association of farm-level agricultural biodiversity with diet diversity and quality among women of reproductive age in Peru and 2) determine the extent to which farm market orientation mediates or moderates this association. Methods: We surveyed 600 households with the use of stratified random sampling across 3 study landscapes in the Peruvian Andes with diverse agroecological and market conditions. Diet diversity and quality among women were assessed by using quantitative 24-h dietary recalls with repeat recalls among 100 randomly selected women. We calculated a 10-food group diet diversity score (DDS), the Minimum Dietary Diversity for Women (MDD-W) indicator, probability of adequacy (PA) of 9 micronutrients by using a measurement-error model approach, and mean PA (MPA; mean of PAs for all nutrients). Agricultural biodiversity was defined as a count of crop species cultivated by the household during the 2016–2017 agricultural season. Results: In regression analyses adjusting for sociodemographic and agricultural characteristics, farm-level agricultural biodiversity was associated with a higher DDS (incidence rate ratio from Poisson regression: 1.03; P < 0.05) and MPA (ordinary least-squares ß-coefficient: 0.65; P < 0.1) and higher odds of achieving a minimally diverse diet (MDD-W: OR from logistic regression: 1.17; 95% CI: 1.11, 1.23) and a diet that met a minimum threshold for micronutrient adequacy (MPA >60%: OR: 1.21; 95% CI: 1.10, 1.35). Farm market orientation did not consistently moderate these associations, and in path analyses we observed no consistent evidence of mediation of these associations by farm market orientation. Conclusions: Farm-level agricultural biodiversity was associated with moderately more diverse and more micronutrientadequate diets among Peruvian women. This association was consistent across farms with varying levels of market orientation, although agricultural biodiversity likely contributed to diets principally through subsistence consumption.
