This research examines the significance of restoring efficient water management systems in India’s semiarid environment, with special emphasis on role traditional irrigation structures, such as tanks, collecting and storing limited resources.

Background: Despite health benefits to both infants and mothers, many are not breastfeeding as recommended by national guidelines. Prior studies examining the effects of housing insecurity food on intention duration have been limited yielded mixed findings. Methods: To assess relationship among insecurity, breastfeeding, we conducted a secondary analysis cohort nulliparous U.S.-born pregnant individuals with singleton gestation ≥28 weeks who completed web-based surveys five occasions over their infant's first year life. Upon enrollment, screened participants for participation in Special Supplemental Nutrition Program Women, Infants, Children (WIC). We examined variations intentions practice controlling demographic factors, using multivariable logistic regression. Results: Of 411 participants, 67 (16%) reported 48 (12%) insecurity. Participants were less likely report exclusive at 6 months (17.9% versus 29.1%, p = 0.06) significantly any 12 (34.3% 56.9%, 0.003) compared those secure housing. In bivariate models, was associated cessation before months. Food or exclusivity. Conclusions: Housing is may adversely impact infant feeding, highlighting need screening accessible affordable family housing, further investment assistance programs such WIC.
