Body composition reference percentiles of healthy Iranian children and adolescents in southern Iran.
The prevalence of childhood obesity has risen greatly worldwide. However, assessment of obesity among children and adolescents is further complicated by the changes occurring in the body composition during the growth. The aim of this study is to create gender-specific percentile curves for total body fat percentage (TBFP), total body fat mass (TBFM), fat mass index (FMI), and fat free mass index (FFMI) in healthy Iranian children and adolescents. ⋯ This study presents normative data for body composition in healthy Iranian children and adolescents and would be useful in adiposity assessment. Our study showed that Iranian children and adolescents had lower total body fat in all age groups and percentiles in comparison with those reported from western children.

Following MPOWER's 2011 report, a study was conducted to quantify the implementation of MPOWER tobacco control policies in the Eastern Mediterranean Region (EMR) in 2013 to assess any possible change during the last two years. ⋯ There has been a slight overall improvement in tobacco control planning, although the desired levels have yet to be reached and some countries in the region have fared worse.

Gastrointestinal lymphoma is the most common type of extranodal non-Hogkin's lymphoma. The proportion and different types of primary extranodal gastrointestinal non-Hodgkin's lymphoma are different in various geographic locations. Therefore, in this study we tried to evaluate the various types of extranodal gastrointestinal non-Hodgkin's lymphoma in affiliated hospitals of the Shiraz University of Medical Sciences as the largest referral center in the southern Iran. ⋯ The pattern of gastrointestinal lymphoma in Iran is very similar to the Western countries. Compared with 40 years ago, it seems that the epidemiology of this lymphoma has changed.

Evaluating trends in blood donors' infectious diseases is essential for monitoring the safe supply of blood, donor screening effectiveness, and the occurrence of infections in the blood donor population which consequently gives an idea of the epidemiology of these diseases in the community. The aim of the present study was to assess the prevalence of hepatitis B, hepatitis C, HIV and syphilis by carrying out confirmatory tests in Tehran's blood transfusion center between 2005 and 2011. ⋯ Declining trend in prevalence of blood-borne infections indicates the effectiveness of screening methods and selection of appropriate donors. Higher prevalence of blood-borne infections in males, low educated, married, first-time donors and donors who referred to the mobile centers requires a different planning in these groups.

The extensive rise in the prevalence of obesity is a matter of great concern and poses a global threat to people's health. Obesity and overweight are considered to be the consequence of a collection of conditions including genetic, social, environmental, behavioral, and physical factors. The aim of this study was to investigate the determinants of weight change over seven years in a prospective study in an Iranian population. ⋯ Our data showed that multiple factors affect weight change, among which age, smoking, and education are important determinants in Iranian adults.
