ABSTRACT
Healthy eating and physical activity habits formed during childhood can persist into adulthood and prevent or delay premature onset of a number of chronic diseases. The aim of this study was patterns of physical activity and dietary habit in relation to weight status in adolescent girls. In a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 Semnan secondary schools. Weigh and height were measured and Body Mass Index [BMI] was calculated. In adolescents, anthropometric indices were defined based on the CDC 2000 cut-off points for age and gender-specific BMI. Data of energy and nutrient intake was collected with the 24-hour dietary recall and food record questionnaires. The food frequency questionnaire was used to evaluate daily food consumption. Physical activity was determined using Baecke questionnaire. Data analyzed indicated that daily fat intake [p=0.003, r=+0.18], energy percent of fat [p=0.04, r=+0.01] and fast food frequency [p=0.026, r=+0.139] had significant relationship with BMI percentile. There was a significant relationship between snack frequency and weight status in high school adolescent girls [p=0.023]. Data analyzed indicated that physical activity had significant relationship with weight status in adolescent girls [p= 0.0001]. The findings suggest that make physical activity enjoyable and improvement food habit among adolescent girls are necessary to induct
ABSTRACT
Nutritional status during adolescence plays an important role in human lifecycle. The aim of this study was Nutritional status and dietary intake among adolescent girls. In a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 Semnan secondary schools. Weight and height were measured and body mass index [BMI] was calculated. In adolescents, anthropometric indices were defined based on the CDC 2000 cut-off points for age and gender-specific BMI. Data of energy and nutrient intake was collected with the 24-hour dietary recall and food record questionnaires. The results showed that the prevalence of underweight, normal weight, overweight, and obese was 5.7%, 77.7%, 11.7%, and 4.7% in Semnan adolescent girls, respectively. In comparison with DRI recommended values, the intake of energy and some micronutrients such as vitamin B12, folate, calcium, zinc, and fiber was insufficient among adolescent girls in Semnan. Malnutrition [underweight and overweight] is higher than the expected rate. Findings of our study showed that micronutrients deficiency among adolescent girls is a major problem among adolescent girls in Semnan and prevention measures are necessary to induct
ABSTRACT
Objectives: Malnutrition among adolescents is not only an important health problem but also an economic development problem in Iran and other developing countries. The home environment is found to be related to the development of malnutrition in children. Information on this relationship is important to identify the target risk groups for nutritional intervention. The objective of this study was to determine the association between socioeconomic with BMI status in Middle school adolescent girls in Kish Island
Methods: In a cross- sectional study, without sampling, 488 girl students aged 11-15 years were selected from all Kish Island Middle schools. Weight and height were measured and BMI was calculated. Weight status was determined based on the CDC 2000 reference for BMI-for-age. Data on socioeconomic factors like age, parental education, and parental job was collected through a questionnaire
Results: Father's literacy and mother's literacy had significant association with BMI status [P=0.001, P=0.06 respectively]. Analyses by chi-square and Pearson correlation tests showed mother's literacy and father's literacy were strong predictors for overweight and obesity
Conclusion: Increasing parental nutritional knowledge is necessary to initiate changes in nutritional conduct. In addition, a longitudinal study of adolescent nutrition and its associated factors is suggested
