Background: Children's height growth is a crucial indicator of health, influenced by parents' beliefs and practices regarding nutrition, physical activity, and sleep. This research aimed to explore parental views on height growth beliefs in families to identify misunderstandings for targeted health education.
Methods: This cross-sectional observational study took place from March to August 2024 at a pediatric outpatient clinic in Mashhad, Iran, involving 200 parents (100 fathers and 100 mothers) of children aged 1 month to 15 years. Data were gathered using a 10-item checklist evaluating beliefs about sports, sedentary activities, sleep, genetics, and nutrition. Statistical analysis included descriptive statistics and chi-square tests to explore the relationship between beliefs and demographic characteristics, such as age and education level.
Results: The majority of parents showed a correct understanding of the benefits of sleep, team sports, and dairy for height growth. However, misconceptions were common, such as associating certain sedentary activities and gymnastics with negative effects on height. Over half believed excess red meat harms growth, and many dismissed the importance of afternoon naps. Fathers’ academic education was linked to beliefs about meat, but no significant links were found for mothers’ education or age.
Conclusions: Significant gaps exist between evidence-based knowledge and the beliefs of even highly educated Iranian parents. While they value sleep and team sports, misconceptions persist about specific physical activities, red meat consumption, and age-appropriate rest. These findings highlight the need for targeted, culturally sensitive educational interventions to correct misconceptions and promote optimal child growth.
