Abstract
BackgroundAdequate daily milk and dairy products intake seems to an important for adolescents’ health. This study aimed to identify the high-risk group adolescents who did not meet the recommended daily serving milk and dairy products and indeed to find out associated factors relating to their nutrition behaviors.MethodsThis cross sectional study was carried out on 7th grade students, in Tabriz, East Azerbaijan province, Iran. An anonymous self–administrated questionnaire including items on perceived social support, physical activity, and sedentary behaviors was administered. In addition a valid food frequency questionnaire (FFQ) measuring daily milk products serving intake as a main outcome measure was completed for each respondent. Logistic regression analysis was applied to examine the association between milk and dairy products consumption and independents variables.ResultsIn all 402 students (51.5 % female) participated in the study. The mean age of students was 12.9 (SD = 0.49) years. The average daily intake of milk and dairy products was 1.64 (SD = 0.78) servings per day. Overall 14.2 % of adolescents (18.8 % of girls, and 9.2 % of boys, p = 0.006) reported consumption of the recommended daily milk and dairy products serving per day. The results indicated that gender boys (OR for boys = 2.41, 95 % CI = 1.25–4.67), mother age (OR for age group 40–55 years = 2.52, 95 % CI = 1.18–5.38), poor perceived emotional family support, (OR = 1.10, 95 % CI = 1.05–3.61), and poor perceived practical family support (OR = 2.04, 95 % CI = 1.18–4.17) were the most significant contributing factors to low level milk and dairy products intake in adolescents.ConclusionThe findings indicated that adolescents did not take the recommended daily amount of milk and dairy products and this appeared to be strongly related to low perceived family support. To achieve the recommended daily milk and dairy products serving consumption, family involvements in any programs that specifically address emotional and practical support for promoting daily milk and dairy products intake among adolescents are suggested.
Highlights
Adequate daily milk and dairy products intake seems to an important for adolescents’ health
When the analysis was performed for girls and boys separately, none of the variables showed significant relationship with low level milk and dairy products consumption in boys (Table 4), while for girls (Table 5) we found a significant association between poor milk and diary intakes and low perceived practical family support (OR = 1.08, 95 % CI = 1.04–2.04, P = 0.036)
The findings showed that average daily milk and dairy products consumption among boys and girls participated in the study was lower than the daily-recommended servings per day
Summary
Adequate daily milk and dairy products intake seems to an important for adolescents’ health. This study aimed to identify the high-risk group adolescents who did not meet the recommended daily serving milk and dairy products and to find out associated factors relating to their nutrition behaviors. Consumption of milk and dairy products is associated with numerous health benefits and play an important role in healthy lifestyle through the lifespan [1,2,3]. Iran has a young population (more than 50 % are aged less than 29 years) Despite such a high proportion of young population, there is limited evidence regarding the adolescents’ consumption of healthy diet. The results would be communicated to the health promotion office in ministry of health
