The study aimed to investigate gender inequalities and their health associated factors in world countries. A cross-sectional survey was undertaken using data of United Nations Development Programme (UNDP) and World Health Organization (WHO). The main variable in this study was gender inequality index (GII). All countries were stratified by WHO regions. Pearson correlation coefficient was used to assess the linear correlation between GII and investigated factors by WHO regions. The mean of GII was greater in Africa and lower in Europe region. There was negative significant association between GII and life expectancy at birth and mean years of schooling, prevalence of current tobacco smoking, high blood pressure and overweight and obesity, alcohol consumption rate, and cancer death rate. But there was positive significant association between GII and noncommunicable diseases death rates. In conclusion, gender inequalities, though decreasing over the past decades in world, remain notably greater in Africa and Eastern Mediterranean regions than in Europe. Gender inequality is also an important issue which is related to health factors. Hence, countries will need to focus on public health intervention and equal distribution of economic resources to reduce gender inequality in society.

Background: Even though the screening programs of common morbidities in schoolchildren are routine in many countries, a large number of patients with different problems may be found at school age. Objectives: The current study aimed to investigate the prevalence of nutritional problems such as stunting, underweight and wasting as well as dental caries and hypertension among schoolchildren. Materials and Methods:This cross-sectional study of student's health status assessment was conducted on primary, middle, and high school students of Sarvabad, a city in the West of Iran, in 2012. Nutritional status was determined by using body mass index for age and gender according to the World Health Organization references. Results: Out of 2596 children, 1113 (42.9%) and 1483 (57.1%) were girls and boys, respectively. The prevalence of caries was 62.8% (95% CI: 60.9, 64.6) with a decayed, missing and filled tooth (DMFT) mean of 0.74 (95% CI: 0.71, 0.76). Totally, 16.41% of the study samples had gingivitis. The prevalence of wasting, underweight, and stunting among schoolchildren was 3.1%, 9.48% and 2.85%, respectively. Hypertension was detected in 5.55% (95% CI: 4.67, 6.43). The prevalence of caries, gingivitis, and hypertension was more common in boys than in girls. Conclusions: Although the high prevalence of health disorders was found among schoolchildren, these rates were lower than those of previous studies in other regions. Results of the current study can help health policy makers to design educational programs concerning dental and public health interventions to deal with nutritional problems in children.
