Background: Proper nutrition and monitoring of growth milestones are critical for ensuring optimal child health and development. This study aims to evaluate the awareness and understanding of nutritional requirements and growth milestones among the general population of Chamba, identifying gaps to inform targeted interventions.Materials and Methods: A descriptive, cross-sectional study was conducted among 400 residents of Chamba district between August and October 2024. Participants were selected through purposive sampling, ensuring representation from diverse socio-demographic backgrounds. Data were collected using a pre-validated structured questionnaire divided into two sections: socio-demographic details and knowledge assessment. The questionnaire included 20 multiple-choice questions on nutrition and growth milestones, with correct answers categorized as Very Good (>80%), Good (60–79%), Fair (41–59%), and Poor (<40%). Data were analyzed using Microsoft Excel and Epi Info V7 for descriptive statistics and chi-square tests.Results: The study had 55% female and 45% male participants, predominantly aged 26–45 years (60.5%), with 66.5% residing in rural areas. Educational attainment varied, with 27.5% holding undergraduate degrees but 12.5% reporting no formal education. While most participants recognized key nutritional practices such as the importance of iron (78%) and exclusive breastfeeding (81.5%), knowledge of technical aspects like growth monitoring frequency (68%) and age-specific milestones (67.5%) was moderate. Knowledge scores revealed that 27% demonstrated very good awareness, 36% good, 29% fair, and 8% poor knowledge, highlighting significant gaps in understanding.Conclusion: The findings underscore a foundational understanding of nutrition and growth milestones among the population, but critical knowledge gaps persist, particularly in technical areas and among less educated groups. Addressing these gaps through targeted community health education, integration of nutrition programs into healthcare services, and leveraging digital tools can empower families to support child development effectively.
