Abstract

Adolescents are an age group vulnerable to nutritional status issues resulting from an imbalance between energy intake and energy expenditure. Physical activity is one of the factors influencing nutritional status. Low levels of physical activity combined with sedentary behavior can disrupt energy balance, thereby increasing the risk of nutritional problems among adolescents. This study aimed to analyze the relationship between physical activity and nutritional status among adolescents at MTs Nurul Islam, Kediri City. A quantitative method with an observational analytic design and a cross-sectional approach was employed. The study sample consisted of 101 adolescents selected using a stratified proportional random sampling technique. Physical activity was measured using the Physical Activity Questionnaire for Adolescents (PAQ-A), while nutritional status was determined based on Body Mass Index (BMI). Data analysis was performed using the Spearman Rank correlation test. The majority of respondents (n=50; 49.5%) fell into the moderate physical activity category, while the largest group regarding nutritional status (n=55; 54.5%) fell into the underweight category. The analysis results indicated a significant relationship between physical activity and nutritional status among adolescents at MTs Nurul Islam, Kediri City (p=0.007; r=0.268). Physical activity is significantly associated with adolescent nutritional status. These findings demonstrate that physical activity is a factor linked to nutritional status; therefore, it needs to be enhanced through promotive and preventive efforts within the school environment to support optimal nutritional status.

Abstract

Diabetes mellitus is a non-communicable disease whose prevalence continues to increase, including among adolescents. Lifestyle changes, such as consumption of foods high in sugar and fat, lack of physical activity, and the increasing incidence of overweight, can increase the risk of diabetes from an early age. Family support is an important factor in developing healthy lifestyle behaviors as an effort to prevent diabetes in adolescents. This study aims to analyze the relationship between family support and diabetes mellitus prevention behaviors in adolescents at SMPN 1 Banyakan, Kediri Regency. The study used a quantitative design with a cross-sectional approach. A total of 147 seventh-grade students were selected as respondents using a proportional random sampling technique. Data were collected through questionnaires and analyzed using the Spearman Rank test. The results showed a significant relationship between family support and diabetes mellitus prevention behaviors in adolescents with a p-value = 0.001 and a correlation coefficient (r) = 0.281. These findings indicate that the better the support provided by the family, the better the diabetes prevention behaviors carried out by adolescents. Therefore, strengthening the role of the family through education and habituation of healthy lifestyle behaviors needs to be optimized as a strategy for preventing diabetes mellitus from adolescence.
