Background: Optimal childhood growth and nutrition are essential for lifelong physical, cognitive, and emotional development. Despite national efforts, India faces persistently high rates of growth deficiencies among children, especially in underserved regions. Himachal Pradesh, with its socio-economic diversity, offers a unique context for understanding public knowledge regarding childhood growth monitoring and nutritional needs. Material & Methods: This descriptive cross-sectional survey was conducted from August to October 2024, targeting adults aged 18 and above who were residents of Himachal Pradesh for at least 12 months. A sample of 400 participants was recruited using online platforms to ensure broad reach. Data were collected through a structured Google Forms questionnaire covering socio-demographic information and knowledge-based questions on childhood growth monitoring, nutrient needs, dietary sources, and common deficiency signs. Each correct response earned one point, with scores categorized as follows: >80% (Very Good), 60-79% (Good), 41-59% (Fair), and <40% (Poor). Statistical analysis of responses was conducted using Epi Info V7 software to calculate frequencies and percentages.Results: The study revealed moderate awareness levels regarding childhood growth and nutrition. While 53.5% of participants could identify essential nutrients necessary for a child’s growth, only 32.5% recognized Vitamin A deficiency's impact on vision, and 44% knew that iron deficiency leads to anemia. Awareness of preventive practices, such as growth monitoring’s role and balanced diet, varied, with 61.5% understanding growth milestones and 48.5% identifying a balanced diet as critical. Knowledge of government nutrition support initiatives was limited, with only 43.5% aware of Anganwadi services and 41.5% familiar with the Midday Meal Scheme. Overall, 24.5% of respondents scored “Very Good,” 36% scored “Good,” 26.75% scored “Fair,” and 12.75% scored “Poor.”Conclusion: This study identified both strengths and critical gaps in public awareness regarding childhood growth monitoring and nutrition in Himachal Pradesh. Limited knowledge of specific nutrient functions and available support programs points to the need for targeted educational campaigns. Initiatives focusing on nutrient-specific education, the preventive role of growth monitoring, and greater visibility of government programs could improve public knowledge and encourage proactive health practices for child development.
