“…In line with previous studies in Iran (19,20), Our findings showed positive relationships between SES with three anthropometric measures, especially at high levels, which revealed that higher risk of overweight/obesity is related to the social environment. Bahreynian et al study reported that the prevalence of overweight was greater in areas with high SES, whereas underweight and short stature were more prevalent in areas with low SES (41). In the current study, students with higher anthropometric measures were living in families with higher SES, as confirmed in some other studies conducted in Iran and some other countries, in which positive significant associations were found between SES and adiposity among children and adolescents in developing countries (20,42,43).…”

Background The present study was conducted to assess some specific factors related to anthropometric indices in a representative sample of Iranian mid-adolescents. It also aimed to investigate the relationship between three anthropometric indices using a multivariate multilevel approach.Methods This study was conducted among 2538 students (1286 boys) aged 14 -20 years old, who were randomly selected among 16 high schools by multi-stage random sampling procedure from 4 education districts of Shiraz, Iran. Data on demographic characteristics and anthropometric measures were collected. Anthropometric indices were estimated by the calibrated tools. A multivariate multilevel model was used to assess the predictor variables associated with obesity measures of the triceps (TST), abdominal (AST), and subscapular (SST) skinfold thickness.Results In this study, the prevalence of overweight and obesity was estimated to be 10.2 and 5.1%, respectively. Hierarchical models showed that, the outcome variables were correlated at the child and district levels. Positive associations were observed between the sex, family history of obesity, and moderate and high Socio-Economic Status (SES) with three anthropometric indices. Moreover, there were positive associations between moderate to vigorous physical activities with AST and SST, but they were not statistically significant at a significance level of 0.05.Conclusions Our findings revealed that, TST, AST, and SST could be useful indices for measuring the adiposity in mid-adolescents. In addition, the effect of the district level on the predictor variables highlights the important role of the environmental factors on the childhood obesity.

“…Some environmental factors including parental overweight, shared family lifestyle, dietary habits, and socio-economic status (SES) are linked to childhood overweight (7,18,19,20,21). Previous studies have indicated that low SES families have little access to healthy foods; therefore, their consumption of high-calorie, low nutrient foods is higher than that of high SES groups (22,23).…”

Objective:This study aims to assess the relationship between body mass index (BMI) of children and that of their parents in a nationally-representative sample of Iranian population.Methods:This cross-sectional nationwide study was conducted in 2011-2012 among 6-18-year-old students and their parents living in 30 provinces of Iran. Socio-demographic information was collected. The BMI values of the children/adolescents were categorized according to the World Health Organization reference curves. Association between parental and student weight status was examined using ordinal regression models after adjustment for potential confounders.Results:Overall, 23043 children and adolescents and one of their parents participated in this study (50.7% boys, 73.4% urban status). Mean age of the subjects was 12.55±3.31 years. Mean BMI values of parents and children/adolescents were 27.0±4.57 and 18.8±4.4 kg/m2, respectively. After adjusting for confounders, overweight and/or obesity in students of both genders was found to be significantly associated with parental overweight and/or obesity. In those students who had obese parents, the odds ratio (OR) of being obese was 2.79 for boys [OR=2.79; 95% confidence interval (CI)=2.44-3.20] and 3.46 for girls (OR=3.46; 95% CI=3.03-3.94) compared to their peers with normal-weight parents. Boys with overweight parents were 1.7 times more overweight than their counterparts with normal-weight parents (OR=1.70; 95% CI=1.15-1.92). Similarly, girls who had overweight parents were more overweight compared to those with normal-weight parents (OR=2.00; 95% CI=1.77-2.25).Conclusion:Our findings highlight the importance of the shared family environment as a multi-factorial contributor to the childhood obesity epidemic and the necessity of implementing family-centered preventive programs.

“…Previous studies considered these two factors and employed the principle component analysis method to divide the country into four large regions. In this study, based on SES, Iranian regions were ranked from highest to lowest as follows: central, west, north-northeast, and southeast [ 29 , 30 ]. The prevalence of wasting is in accordance with the SES of these regions.…”

Purpose Wasting and underweight are the 2 main indicators of children’s undernutrition. We aimed to estimate the prevalence of undernutrition at the national level in Iran.Methods We performed a search for original articles published in international and Iranian databases including MEDLINE, Web of Science, Google Scholar, Scopus, CINHAL (Cumulative Index to Nursing and Allied Health Literature), Scientific Information Database, Irandoc, Iranmedex, and Magiran during January 1989–August 2017. Seven keywords, in English and Persian, including malnutrition, protein energy malnutrition, growth disorders, underweight wasting, weight loss, children below 5 years old, and children, were used to search the databases.Results Finally, 17 articles were included in the meta-analysis, based on which the prevalence of underweight and wasting in Iranian children were estimated to be 11% and 5%, respectively. The prevalence rates of underweight among children in the central, western, southern, and northern parts of Iran and at the national level were 24%, 5%, 20%, 17%, and 6%, respectively. The prevalence rates of wasting in the central, western, southern, and northern parts of Iran and at the national level were 9%, 4%, 11%, 5%, and 4%, respectively.Conclusion Although the prevalence of underweight and wasting in Iran was low, some parts of the country showed high prevalence. The main reason behind this difference in the prevalence of malnutrition may be due to the level of development in different regions.

Prevalence of Growth Disorders in a Nationally Representative Sample of Iranian Adolescents According to Socioeconomic Status: The CASPIAN-III Study

Abstract: Excess weight was more prevalent in high SES regions, whereas underweight and short stature were more prevalent in low SES regions. These findings underscore the necessity of implementing evidence-based health promotion programs and preventive strategies according to SES.
