Abstract Background Handgrip strength is an easy-to-assess indicator of overall muscle strength and can be used to evaluate health status. Although previous studies have reported an increase in grip strength due to aerobic exercise, such a study has not been conducted on Korean participants. This study aimed to investigate the effects of aerobic exercise on handgrip strength and examine the association between these two variables in Korean patients with hypertension or diabetes. Methods This cross-sectional study used data from the 6th and 7th Korean National Health and Nutrition Examination Survey (2014–2017). A total of 19,650 individuals aged ≥19 years who had responded to questionnaires concerning aerobic exercise and handgrip strength were analyzed. The relationship between aerobic activity and handgrip strength was examined by logistic regression analysis. Results The mean age of individuals in the low muscle strength group was higher than that in the normal muscle strength group. The odds ratio for low handgrip strength was higher in individuals who did not perform aerobic exercise than in those who performed aerobic exercise. Following adjustment for covariates, the odds ratios (95% confidence intervals) for low handgrip strength were 1.415 (0.187–1.688) in the total sample, 1.799 (1.376–2.352) in patients with hypertension, and 1.811 (1.208–2.715) in patients with diabetes. Conclusion The results of our study indicated a strong association between aerobic exercise and handgrip strength in the Korean population.

ObjectiveTo explore the association between age-related macular degeneration (AMD) and arthritis in a representative sample of the US population.DesignPopulation-based, cross-sectional study.SettingThe National Health and Nutrition Examination Survey (NHANES) 2005–2008.ParticipantsA total of 4813 participants aged 40 years and older with available information on AMD and arthritis in the 2005–2008 NHANES.MethodsThe status and types of arthritis were obtained from questionnaires. Non-mydriatic fundus photographs were collected. The types of AMD were assessed using the modified Wisconsin Age-Related Maculopathy Grading Classification Scheme. The association between arthritis and AMD was evaluated using logistic regression models.ResultsAfter adjusting for covariates, participants with any or early AMD had significantly lower odds of having any type of arthritis (any AMD: OR=0.56, 95% CI: 0.36–0.86; early AMD: OR=0.55, 95% CI: 0.34–0.88) or osteoarthritis (OA) (any AMD: OR=0.43, 95% CI: 0.26–0.71; early AMD: OR=0.44, 95% CI: 0.25–0.76) compared with those without AMD. When considering AMD as the outcome, significant negative associations were also found between any arthritis or OA and any (any arthritis: OR=0.64, 95% CI: 0.43–0.94; OA: OR=0.52, 95% CI: 0.33–0.82) or early AMD (any arthritis: OR=0.61, 95% CI: 0.40–0.93; OA: OR=0.51, 95% CI: 0.31–0.86) in the multivariable logistic models. There was no significant association between different types of arthritis and late AMD.ConclusionsPeople with arthritis, especially those with OA, were less likely to have AMD compared with those without arthritis and vice versa. Further studies are needed to confirm this potential protective effect of arthritis and/or arthritis treatment on AMD and to explore the underlying mechanisms.
