Malnutrition from poor diet is a persistent issue in Sri Lanka, especially among women and children. High rates of undernutrition and micronutrient deficiencies are documented among rural poor communities(1). Household food production may enhance maternal and child nutrition directly by increasing access to diverse foods and indirectly by providing income to diversify diets(2). This study explores the cross-sectional relationship between household food production and individual dietary diversity among women aged 18-45 years and children aged 2-5 years in Batticaloa district, Sri Lanka. We randomly selected 450 low-income mother-child pairs receiving a Samurdhi subsidiary, having a home garden. Through face-to-face interview, we gathered information on the types of crops grown and livestock reared in the preceding 12 months. Production quantity and utilization were also detailed. Additionally, socio-demographic information and market access were obtained. To measure women’s dietary diversity (DD), we used a scale based on 10-food groups and a 7-food group scale for children. Women who consumed five or more food groups were defined as meeting the Minimum Dietary Diversity of Women (MDD-W), whereas children who consumed of four or more food groups met the minimum standards. Multiple linear regression and binary logistic regression were used to identify the factors predicting individual DD. Complete data for 411 pairs were analysed. The results showed, only 15.3% of the women met MDD-W, with a mean DDS of 3.3 (SD = 1.2). Children had a mean DDS of 3.3 (SD = 1.2), and 41.1% of them met the minimum diversity. Regression analysis indicated that growing leafy vegetables was positively associated with increased dietary diversity of women (β = 0.337; 95% CI: 0.13, 0.54; p = 0.001) and children (β = 0.234; 95% CI: 0.05, 0.42; p = 0.013) but not with meeting the minimum diversity. Moreover, monthly income above 35,000 LKR, higher education level, a secondary income source andfood security were also positively associated with women’s DD. Conversely, living further away from the main road reduced the women’s DD. Interestingly, livestock ownership was only associated with women meeting the MDD-W, but not for children. For children, monthly income was a strong predictor of DD and meeting minimum diversity. Surprisingly, living far from the market was associated with increased DD in children (β = 0.018; 95% CI: 0.01, 0.03; p = 0.013), while distance to main road had a similar effect as in women. Notably, selling their produce at the market contributed to meeting the minimum dietary diversity in children (β = 0.573; 95% CI: 0.14, 1.02; p = 0.013). These findings suggest that enhancing household food production could play a crucial role in improving dietary diversity and addressing malnutrition, particularly in rural Sri Lankan communities, and potentially in other similar settings.

Household food production is considered a key avenue for improving food security and nutritional status, particularly for low-income people from developing countries. However, little is known about what aspects of home garden production enhance nutritional outcomes. This paper aims to assess how home gardens influence nutritional status while considering the impact of various child, maternal, and household characteristics such as birthweight, age, education, and income. We also examined the impact of distance to the market mediating this association. We conducted a cross-sectional study of 403 children (24-60 months) and their mothers (18-45 years) in Batticaloa district, Sri Lanka using a pre-tested structured questionnaire. Maternal and child anthropometric measures were taken, and children were classified as stunted, wasted and underweight based on the WHO references, and BMI was calculated for mothers(1). Logistic regression was used to analyse the factors associated with the dependent variable, nutritional outcomes. Food production diversity was not associated with maternal or child nutritional outcomes. The only production variable associated with child nutritional outcome was livestock ownership, and it was negatively associated with child wasting (P < 0.01). Surprisingly, increased market distance improved the child undernutrition (P <0.05). Higher levels of maternal education were significantly associated with reducing stunting and underweight in children (P < 0.01). Childbirth weight showed a negative association with a child underweight (P < 0.01), and we also observed a small negative effect of a child’s age on stunting. These findings suggest that while home gardens can be an entry point, improving nutrition may require a multifaceted approach that addresses a broader range of factors.

The aim of this study was to evaluate the antifungal spectrum of activity, synergy, and mode of action of carboxy-terminally amidated antimicrobial peptides (AMPs) derived from tachyplesin-I (T-I) from the horseshoe crab Tachypleus tridentatus and a lysine-rich analogue of magainin-2 (MSI-94) from the clawed frog Xenopus laevis. In vitro antimicrobial tests against 17 fungal strains demonstrated that the modified AMPs exhibited broad antifungal activity, particularly against filamentous fungi and yeasts relevant to aquaculture and agriculture. Additive antimicrobial activity was observed with the combination of T-I and MSI-94 against Candida albicans and Rhodotorula mucilaginosa, indicating an enhancement of their antiyeast properties. Furthermore, we found that both peptides target the fungal cell surface, increasing membrane permeability and leading to cell death. Overall, our findings highlight the biotechnological potential of aquatic AMPs in developing novel antifungal therapeutics applicable across various fields.
