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


Information had been produced from the 2016 Korean Study of Women’s Health-Related problems. The chi-square ensure that you logistic regression analysis were utilized to evaluate the associations between socioeconomic facets and obesity making use of 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 general index of inequality (RII) had been determined, with modification for age and self-reported wellness status.


Korean females had been categorized in to the after BMI categories: underweight (5.3%), normal fat (59.1%), obese (21.2%), and obese (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 very educated (SII, -16.7; RII, 0.3). Subgroup analysis revealed inequalities in obesity based on home earnings among more youthful ladies and in accordance with urbanization among ladies aged 65-79 years.


Clear academic inequalities in obesity existed in Korean ladies. Reverse inequalities in urbanization were additionally apparent in older ladies. Developing methods to deal with the numerous inequalities that are observed obesity among Korean females may show required for efficiently decreasing the burden for this illness.


Obesity, which will be increasing in prevalence internationally, is a condition that is physical by the accumulation of excessive fat in the body, along side a great many other wellness impairments. Obesity was discovered to adversely influence an extensive spectral range of conditions, from non-communicable problems to psychological and social wellness, including diabetes, malignancies, depression, discrimination, as well as others 1-4. The harmful effects to be obese or overweight are found become particularly 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 now been discovered to alter based on parameters showing variations in socioeconomic status, such as for example urbanization, education, and earnings amounts. Females surviving in urbanized areas and residing in socioeconomically-deprived conditions happen reported to show faster increases within the prevalence of obesity and overweight 9-13. Notwithstanding, the direction and magnitude of effects of socioeconomic facets on inequalities in obesity might differ across countries 14-16. In united states and countries in europe, inequalities pertaining to obesity have generally speaking been well documented; obesity happens to be discovered become disproportionately more frequent among individuals with reduced amounts of training and earnings, residents of less urbanized areas, and the ones access that is lacking medical 10,15. In comparison, although just a few research reports have addressed socioeconomic inequalities in obesity in developing nations, many findings of these nations suggest contrasting results education that is regarding earnings status (in other words., greater obesity prices in females with advanced schooling and home income) 16. In light regarding the link between a study that is prior socioeconomic factors affect obesity status in many ways that vary by nation, it is vital to start thinking about exactly just how these socioeconomic facets affect obesity to build up wellness advertising programs.

Into the Republic of Korea (hereafter Korea), the prevalence of obesity happens to be formally surveyed utilizing human anatomy mass 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 leaner than that of guys, Korean women over the age of 65 years have actually greater obesity rates than males of a age 18 that is similar. Also, while BMI in Korean men slowly increases as we grow older, in Korean females, it sharply increases following the chronilogical age of 40 years and menopause 17. Also, inspite of the stable findings regarding 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, particularly for females aged two decades to 59 years 17.

While obesity prices in Korea are notably less than those of other Organization for Economic Cooperation and developing nations, socioeconomic inequalities in obesity remain a place of discussion 10. Outcomes from past studies, nonetheless, reflect outdated data 10,19 and offer incomplete conclusions on inequality because of the utilization of restricted inequality indicators 19. For the part that is most, those studies adopted mainstream logistic analyses or direct easy evaluations of price distinctions (extra danger) or ratios involving the greatest and cheapest socioeconomic groups. But, the original approach of comparing extreme groups in the socioeconomic range fails to consider modifications over the complete array of socioeconomic teams. In this research, we used the slope index of inequality (SII) while the general index of inequality (RII), that are regression-based measures of wellness status across all ranges of every socioeconomic element 20. Additionally, although past documents emphasized the discrepancies of obesity patterns by sex, they dedicated to explaining mechanisms of obesity in Korean adult guys as a result of greater prevalence of obesity in men 10,19.

Therefore, in this research, we aimed to report the prevalence of obesity among Korean adult ladies aged 19 years to 79 years utilizing current nationally representative information. We additionally desired to analyze associations between socioeconomic facets and obesity in Korean ladies. In specific, we examined current socioeconomic inequalities in obesity among Korean ladies in accordance with home earnings, training degree, and urbanization (location of residence) via absolute and general indicators specialized for inequality analysis.
