Relationship of Breastfeeding Duration with Joint Pain and Knee Osteoarthritis in Middle-aged Korean Women: A Cross-sectional Study using the Korea National Health and Nutrition Examination Survey

Abstract Background The effect of joint health on the quality of life of middle-aged and older women is becoming more widely recognized with the aging of the world’s population. However, the association of long-term breastfeeding with joint pain and knee osteoarthritis has not been fully examined. The aim of this study was to determine the association of prior breastfeeding duration with current joint pain and knee osteoarthritis in middle-aged Korean women. Methods This cross-sectional study was conducted among 3,454 women aged ≥50 years who underwent knee radiography and answered a questionnaire on breastfeeding and joint pain for the 5th Korea National Health and Nutrition Examination Survey (2010–2011). After adjusting for confounding sociodemographic, medical history, and obstetric and gynecologic variables, logistic regression analysis was conducted to analyze the prevalence of joint pain and knee osteoarthritis according to breastfeeding and its duration. Results Among the 3,454 participants, 298 had not breastfed and 1,042, 815, and 1,299 had breastfed for 1–24, 25–48, and ≥49 months, respectively. Of all participants, 1,731 had joint pain and 739 were diagnosed with knee osteoarthritis after radiography.The odds ratio (OR) for joint pain among women who breastfed was 1.49 (95% confidence interval [CI] 1.01-2.21). As the breastfeeding duration increased, the OR of joint pain prevalence also increased (p for trend; p=0.002). For knee osteoarthritis, the OR was 2.30 in the 25–48 months group (95% CI 1.09-4.86). The OR of knee osteoarthritis in the ≥49 months group was 2.17 (95% CI 1.01-4.64). Sensitivity analysis after selecting only participants aged ≥60 years showed that the prevalence of joint pain and knee osteoarthritis was more positively correlated with extended breastfeeding duration (joint pain, p for trend; p=0.005) (knee osteoarthritis, p for trend; p=0.012).Conclusions Long-term feeding for more than 25 months was associated with an increased prevalence of arthralgia and degenerative arthritis in Korean women aged ≥50 years.

After adjusting for confounding sociodemographic, medical history, and obstetric and gynecologic variables, logistic regression analysis was conducted to analyze the incidence of joint pain and knee osteoarthritis according to breastfeeding and its duration. Among the 3,454 participants, 298 had not breastfed and 1,042, 815, and 1,299 had breastfed for 1–24, 25–48, and ≥49 months, respectively. Of all participants, 1,731 had joint pain and 739 were diagnosed with knee osteoarthritis after radiography. Results The odds ratio (OR) for joint pain among women who breastfed was 1.493 times higher than that among women who did not (p=0.044). As breastfeeding duration increased, the OR of joint pain incidence also increased (p for trend; p=0.002). For knee osteoarthritis, the OR was significantly different between the 25–48 and ≥49 months groups (2.299 [p=0.03] and 2.166 [p=0.047], respectively). Reanalysis after selecting only participants aged ≥60 years showed that the prevalence of joint pain and knee osteoarthritis was more positively correlated with extended breastfeeding duration (joint pain, p for trend; p=0.005) (knee osteoarthritis, p for trend; p=0.012). Conclusions Long-term feeding of more than 25 months was associated with an increased prevalence of arthralgia and degenerative arthritis after menopause in Korean elderly women.

ObjectivesTo examine trends in socioeconomic inequalities in major cardiovascular disease (CVD) risk factors among the Korean population.DesignCross-sectional study.SettingA nationally representative population survey database.ParticipantsA total of 42 725 Koreans, aged 25–64 years, who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) II (2001) to VI (2013–2014).Main outcome measuresTrends in socioeconomic inequalities in five major CVD risk factors (smoking, obesity, diabetes, hypertension and hypercholesterolaemia).ResultsGender differences were noted in the time trends in socioeconomic inequalities in smoking, obesity, diabetes and hypertension. Among men, low socioeconomic status (SES) was associated with higher prevalence of smoking, but not with obesity, diabetes or hypertension. The magnitudes of socioeconomic inequalities in smoking, obesity and diabetes remained unchanged, and the magnitude of the inequality in hypertension decreased over time. However, among women, low SES was associated with higher prevalence of smoking, obesity, diabetes and hypertension. Time trends towards increasing socioeconomic inequalities, measured by income, in smoking, obesity and diabetes were found in women. Unlike the other CVD risk factors, hypercholesterolaemia was not associated with socioeconomic inequality.ConclusionsSES had a stronger impact on major CVD risk factors among Korean women than men. Moreover, socioeconomic inequalities in smoking, obesity and diabetes worsened among Korean women over time. Public policies to prevent smoking, obesity and diabetes in women with lower SES are needed to address inequalities.
