Determinants of complementary feeding practices among children aged 6-24 months in urban slums of Pune, Maharashtra, in India.

Background: Inequalities in child feeding practices are evident in urban slums in developing nations. Our study identified the determinants of complementary feeding (CF) practices in the informal settings of Pune, India, a district close to the business capital of India.

Methods: Employing a cross-sectional study design, 1066 mother-children dyads were surveyed. Five indicators defined by the WHO were used to study complementary feeding practices. Determinants of complementary feeding practices were identified using multivariate analyses.

Results: Timely initiation of CF was reported by 42%. Minimum acceptable diet (MAD), minimum meal frequency (MMF), and Diet Diversity Score > 4 were achieved by 14.9%, 76.5%, and 16.4%, respectively. Continued breastfeeding (CBF) at 2 years, and feeding processed foods were practiced by 94% and 50%, respectively. Among the maternal characteristics, a mother's age > 30 years at pregnancy was less likely to achieve DD [AOR: 0.195 (CI 0.047-0.809)] and MAD [AOR: 0.231 (CI 0.056-0.960)]. Mothers with lower education were less likely to meet MMF [AOR: 0.302 (0.113-0.807)], MAD [AOR: 0.505 (CI 0.295-0.867)] and to introduce formula feeds (FF) [AOR: 0.417 (0.193- 0.899)]. Among obstetric characteristics, birth spacing < 33 months was less likely to achieve DD [AOR: 0.594 (CI 0.365-0.965)] and CBF [AOR: 0.562 (CI: 0.322-0.982)]. Receiving IYCF counseling only during postnatal care hindered the timely initiation of CF [AOR: 0.638 (0.415-0.981)]. Very Low Birth Weight increased the odds of achieving DD [AOR: 2.384 (1.007-5.644)] and MAD [AOR: 2.588(CI: 1.054-6.352)], while low birth weight increased the odds of children being introduced to processed foods [AOR: 1.370 (CI: 1.056-1.776)]. Concerning socio-economic status, being above the poverty line increased the odds of achieving MMF, [AOR: 1.851 (1.005-3.407)]. Other backward castes showed higher odds of achieving MAD [AOR: 2.191 (1.208-3.973)] and undisclosed caste in our study setting decreased the odds of FF [AOR: 0.339 (0.170-0.677)]. Bottle feeding interfered with MMF [AOR: 0.440 (0.317-0.611)] and CBF [AOR: 0.153 (0.105-0.224)].

Conclusion: Investing in maternal education and IYCF counseling during both ANC and PNC to provide nutritious complementary foods alongside addressing poverty should be a national priority to prevent the double burden of undernutrition at an early age in informal settings.
