Whilst 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 examine the current prevalence of obesity in Korean females aged between 19 years and 79 years also to evaluate socioeconomic inequalities in obesity.


Information had been produced by the 2016 Korean Study of Women’s Health-Related problems. The chi-square ensure that you 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 ). The slope index of inequality (SII) and relative index of inequality (RII) were calculated, with adjustment for age and self-reported health status as inequality-specific indicators.


Korean females had been categorized 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 who have been very educated (SII, -16.7; RII, 0.3). Subgroup analysis revealed inequalities in obesity in accordance with home earnings among younger ladies and in accordance with urbanization among females aged 65-79 years.


Clear academic inequalities in obesity existed in Korean females. Reverse inequalities in urbanization had been additionally apparent in older females. Developing strategies to deal with the numerous noticed inequalities in obesity among Korean ladies may show necessary for effortlessly reducing the responsibility of the condition.


Obesity, that will be increasing in prevalence all over the world, is really a health characterized because of the accumulation of exorbitant surplus fat, along with a number of other health impairments. Obesity happens to be discovered to adversely influence a broad spectral range of diseases, from non-communicable problems to mental and social wellness, including diabetic issues, malignancies, depression, discrimination, yet others 1-4. The harmful effects to be obese or overweight have been discovered become specially harmful in females, elevating risks for reproductive problems, psychological state conditions, and predominantly women’s cancers, such as for instance endometrial and cancer of the breast 5-8.

Disparities in obesity prevalence have already been found to alter based on parameters showing variations in socioeconomic status, such as for instance urbanization, training, and earnings amounts. Ladies moving into urbanized areas and residing 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 facets on inequalities in obesity might differ across nations 14-16. In the united states and countries in europe, inequalities pertaining to obesity have actually generally speaking been well documented; obesity happens to be found become disproportionately more frequent among individuals with reduced amounts of training and earnings, residents of less urbanized areas, and the ones lacking usage of medical 10,15. On the other hand, although only some studies have addressed socioeconomic inequalities in obesity in developing nations, many findings of these nations suggest contrasting outcomes education that is regarding earnings status (in other words., higher obesity prices in females with advanced schooling and home income) 16. In light associated with link between a study that is prior socioeconomic factors affect obesity status in many ways that vary by nation, you should think about just just exactly how these socioeconomic facets affect obesity to build up wellness advertising programs.

Within the Republic of Korea (hereafter Korea), the prevalence of obesity was formally surveyed utilizing human body mass index (BMI) since 1998. The BMI that is mean for ladies slightly increased from 1998 to 2005 and stabilized from 2005 to 2014 17. Even though the general prevalence of obesity in females is gloomier than compared to guys, Korean women more than 65 years have actually greater obesity prices than guys of the comparable age 18. Also, 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. Furthermore, inspite of the stable findings regarding the general prevalence of obesity among Korean ladies, a substantial rise in grade II obesity (BMI ≥ 30.0 kg/m 2 ) from 1998 to 2014 is recorded, specifically for females aged two decades to 59 years 17.

While obesity prices in Korea are significantly less than those of other Organization for Economic Cooperation and developing nations, socioeconomic inequalities in obesity keep on being a spot of discussion 10. Outcomes from past studies, but, mirror outdated data 10,19 and offer incomplete conclusions on inequality becausage of the utilization of restricted inequality indicators 19. For the part that is most, those studies used traditional logistic analyses or direct easy evaluations of price distinctions (extra danger) or ratios involving the greatest and cheapest socioeconomic teams. However, the original approach of comparing extreme groups from the socioeconomic range fails to take into consideration modifications throughout the complete selection of socioeconomic teams. In this research, we used the slope index of inequality (SII) plus the general index of inequality (RII), that are regression-based measures of wellness status across all ranges of each and every socioeconomic element 20. Moreover, although past documents emphasized the discrepancies of obesity patterns by sex, they centered on explaining mechanisms of obesity in Korean adult guys because of the greater prevalence of obesity in men 10,19.

Hence, in this study, we aimed to report the prevalence of obesity among Korean adult females aged 19 years to 79 years utilizing current data that are nationally representative. We additionally desired to research associations between socioeconomic facets and obesity in Korean females. In specific, we examined existing inequalities that are socioeconomic obesity among Korean ladies based on home earnings, training degree, and urbanization (location of residence) via absolute and general indicators specialized for inequality analysis.
