Whilst the prevalence of obesity in Asian ladies has remained stagnant, studies of socioeconomic inequalities in obesity among Asian women can be scarce. This study aimed to look at the prevalence that is recent of in Korean females aged between 19 years and 79 years and also to evaluate socioeconomic inequalities in obesity.


Information had been produced from the 2016 Korean Study of Women’s Health-Related problems. The test that is chi-square logistic regression analysis were utilized to investigate the associations between socioeconomic facets and obesity utilizing Asian standard human body mass index (BMI) groups: low ( 2 ), normal (18.5-22.9 kg/m 2 ), obese (23.0-24.9 kg/m 2 ), and overweight (≥25.0 kg/ m 2 ). As inequality-specific indicators, the slope index of inequality (SII) and relative index of inequality (RII) had been determined, with modification for age and self-reported wellness status.


Korean ladies had been classified in to the after BMI categories: underweight (5.3%), normal fat (59.1%), obese (21.2%), and overweight (14.4%). The SII and RII unveiled significant inequalities in obesity and only more urbanized women (SII, 4.5; RII, 1.4) and against of females have been extremely educated (SII, -16.7; RII, 0.3). Subgroup analysis revealed inequalities in obesity in accordance with household earnings among more youthful females and based on urbanization among ladies aged 65-79 years.


Clear inequalities that are educational obesity existed in Korean females. Reverse inequalities in urbanization had been additionally obvious in older ladies. Developing techniques to deal with the numerous noticed inequalities in obesity among Korean females may show necessary for efficiently reducing the duty of the infection.


Obesity, that is increasing in prevalence around the world, is a health characterized because of the accumulation of excessive excessive fat, along side a great many other wellness impairments. Obesity happens to be found to adversely influence an extensive spectral range of conditions, from non-communicable disorders to psychological and social wellness, including diabetic issues, malignancies, depression, discrimination, yet others 1-4. The harmful effects to be obese or obese are found become specially harmful in females, elevating risks for reproductive problems, psychological state conditions, and predominantly women’s cancers, such as for example endometrial and cancer of the breast 5-8.

Disparities in obesity prevalence have already been discovered to alter relating to parameters showing variations in socioeconomic status, such as for example urbanization, training, and earnings amounts. Ladies moving into urbanized areas and staying in socioeconomically-deprived conditions have now been reported to show faster grows within the prevalence of obesity and overweight 9-13. Notwithstanding, the direction and magnitude of ramifications of socioeconomic factors on inequalities in obesity might vary across nations 14-16. In united states and countries in europe, inequalities pertaining to obesity have actually generally speaking been well documented; obesity happens to be discovered become disproportionately more predominant among individuals with reduced degrees of training and earnings, residents of less urbanized areas, and the ones access that is lacking medical 10,15. In comparison, although only some research reports have addressed socioeconomic inequalities in obesity in developing nations, many findings for those nations suggest contrasting outcomes education that is regarding earnings status (for example., greater obesity prices in females with advanced schooling and home earnings) 16. In light associated with link between a study that is prior socioeconomic factors affect obesity status with techniques that vary by nation, you should give consideration to just just how these socioeconomic factors affect obesity to produce wellness advertising programs.

Within the Republic of Korea (hereafter Korea), the prevalence of obesity happens to be formally surveyed body that is using index (BMI) since 1998. The BMI that is mean for females slightly increased from 1998 to 2005 and stabilized from 2005 to 2014 17. Even though general prevalence of obesity in females is lower than compared to males, Korean women avove the age of 65 years have actually greater obesity prices than males of a age 18 that is similar. Furthermore, while BMI in Korean men slowly increases as we grow older, in Korean ladies, it sharply increases following the chronilogical age of 40 years and menopause 17. Additionally, regardless of the stable findings from the general prevalence of obesity among Korean females, an increase that is significant grade II obesity (BMI ≥ 30.0 kg/m 2 ) from 1998 to 2014 happens to be recorded, specifically for ladies aged twenty years to 59 years 17.

While obesity rates in Korea are significantly less than those of other Organization for Economic Cooperation and developing countries, socioeconomic inequalities in obesity continue being a spot of discussion 10. Results from past studies, but, reflect outdated data 10,19 and offer incomplete conclusions on inequality becautilization of the utilization of restricted inequality indicators 19. When it comes to many part, those studies used mainstream logistic analyses or direct easy evaluations of price distinctions (extra danger) or ratios amongst the greatest and cheapest socioeconomic teams. But, the standard approach of comparing extreme groups in the spectrum that is socioeconomic to take into consideration modifications over the complete array of socioeconomic teams. In this research, we used the slope index of inequality (SII) additionally the general index of inequality (RII), that are regression-based measures of wellness status across all ranges of each and every factor 20 that is socioeconomic. Moreover, although past documents emphasized the discrepancies of obesity habits by sex, they dedicated to explaining mechanisms of obesity in Korean adult males because of the greater prevalence of obesity in men 10,19.

Hence, in this research, we aimed to report the prevalence of obesity among Korean adult females aged 19 years to 79 years making use of present nationally representative information. We also desired to analyze associations between socioeconomic facets and obesity in Korean ladies. In specific, we examined current socioeconomic inequalities in obesity among Korean females based on household earnings, training degree, and urbanization (location of residence) via absolute and relative indicators specialized for inequality analysis.
