JNHRC Vol. 19 No. 1 Issue 50 Jan - Mar 2021 127 Background: Early and late introduction of complementary feeding is associated with increased morbidity and nutritional deficiencies in children. In 2016, the under 5 mortality rate of Nepal was 39 deaths per 1000 live births and around 1 million under 5 children had suffered from chronic malnutrition. The main aim of this study was to identify the level of knowledge and practice regarding complementary feeding among the mothers of children aged 6 to 24 months in Bhanu Municipality, Tanahu District, Nepal. Methods: A descriptive cross-sectional study was conducted with 158 mothers of children age group 6 to 24 months from ward number 1 and 2 in Bhanu Municipality, Tanahu District, Nepal. Data collection was done after taking ethical approvalby using a semi-structured questionnaire via face-to-face interviews. Collected data were entered and descriptive analysis was carried out in Statistical Package for the Social Services version 20. Categorical variables were presented using frequency and percentage. Clopper-Pearson method was used to determine 95% confidence interval. Results: Out of 158 respondents, 26.6% (95%CI:19.9,34.2) had inadequate knowledge, whereas 73.4% (95%CI:65.8, 80.1) had adequate knowledge on complementary feeding. Likewise, the study revealed that 51.9%(95%CI: 43.8, 59.9) did the right practice, while 48.1%(95%CI: 40.1,56.2) were involved in the wrong practice on complementary feeding. Only 39 % mothers gained the knowledge about complementary feeding from the health workers. 2.5% of mother had exclusively breastfed their child up to just 3 months. Conclusions: Despite the good level of knowledge about complementary feeding, the wrong practice was prevalent in about half of the mothers. As a result, enhancing existing strategies and developing new intervention measures including capacity building of healthworkers to improve child feeding practices must be mandatory actions for the government and policymakers.

ABSTRACT J Nepal Health Res Counc 2021 Jan-Mar;19(50): 127-34 INTRODUCTION Child health is closely linked to the baby’s nutritional status. The rate of malnutrition rises between 6 and 18 months—the complementary feeding period. 1 Complementary feeding is a practice started after six months of a child when breast milk alone is insufcient to meet the nutritional requirements of infants. 2 Subsequently, infant should consume nutritionally sufcient and nutritious complementary diets to fulfll their changing nutritional needs, while continuing to breastfeed for up to two years or longer. 3 Studies in Nepal have shown lack of knowledge about the right time of complementary feeding either to feed after or before 6 months and right practice of complementary feeds at frst six months of a child with continued breastfeeding until twenty four months. 4,5 In this context, a study was conducted to assess the knowledge and practice of complementary feeding among the mothers of children of aged group 6 to 24 months in Tanahun District, Bhanu Municipality.
