This study assessed factors associated with nutritional status of under five children in Rupandehi District of Nepal. It found that over half (45.9%) of children aged 36-59 months were underweight. Nearly half (50%) of children born to illiterate mothers were underweight. The majority (65%) of children were stunted according to Waterlow's classification. Over half (57.75%) of children born to mothers under 18 years old were underweight, as were 75% of children born to mothers over 35 years old, though the association between maternal age and nutritional status was not statistically significant. The study concluded that greater emphasis should be given to under five children through community-based awareness programs for mothers and caregivers
