Health behaviors of people with retinitis pigmentosa in the republic of Korea.

PURPOSE: To investigate the health behaviors of people with retinitis pigmentosa (RP) in the Republic of Korea. METHODS: An online questionnaire was used to survey members of the Korean Retinitis Pigmentosa Society (KRPS), over 3 months from December 2010 to February 2011. Controls were selected from participants of the 4th Korean National Health and Nutrition Examination Survey and were matched with people with RP using the propensity score method to optimize comparative analysis. A semi-structured interview was also conducted with five members of the KRPS to identify potential reasons for physical inactivity and unhealthy diet and to develop effective interventions. RESULTS: A total of 194 eligible people with RP responded to the online survey, and 187 individuals were matched with the control population by propensity score matching. RP subjects reported a lower rate of current smoking and greater use of preventive healthcare services. However, people with RP were more physically inactive (50.8% vs 27.3%, p < 0.001) and consumed more fast food (69.5% vs 58.3%, p = 0.024) than the control population. CONCLUSION: Physical inactivity and fast food consumption were more frequently reported in people with RP than the general population. Efforts to understand the possible reasons and develop interventions to improve these health behaviors are warranted.

Mental health of people with retinitis pigmentosa.

PURPOSE: The purpose of this study was to evaluate and compare the mental health of patients with retinitis pigmentosa (RP) with that of the general population of Korea. METHODS: Online surveys were completed by patients registered with the KRPS (Korean Retinitis Pigmentosa Society), an online organization that promotes research on RP and provides advocacy and online and offline support and information for patients with RP. Control population was selected from the fourth round of the KNHANES (Korean National Health and Nutrition Examination Survey). One hundred eighty-seven patients with RP were matched with the control population using the propensity-score method to optimize comparative analysis. RESULTS: Stress was reported in 51.9% of RP patients and 29.4% of controls (p < 0.001). Depressive mood of at least 2 weeks' duration in the previous year was reported by 34.8 and 17.1% of patients and controls, respectively (p < 0.001). Suicidal thoughts were reported by 38.5 and 12.9% of patients and controls, respectively (p < 0.001), although there was no significant difference in the number of suicide attempts between the groups (2.1 vs. 1.6%, p = 0.703). In multivariate analysis, disability rating was significantly associated with stress (adjusted odds ratio, 0.46; 95% confidence interval, 0.24 to 0.88). CONCLUSIONS: People with RP had poorer mental health than the general population. Further investigations are warranted on the mental health of RP patients, and appropriate welfare services are needed to decrease the impact of mental illness in this population.

The Prevalence of Chronic Diseases among Migrants in Korea According to Their Length of Stay and Residential Status.

BACKGROUND: Migrant health is becoming public health issues, as the migrant populations are increasing and their length of stay is prolonged. This study aims to analyze the differences in prevalence of chronic diseases among migrants according to length of stay and residential status. METHODS: An initial population pool were 3,024 who were assessed with health screening programs by Migrant Health Association. 2,459 migrants were selected for final analysis. Via Stata 10 we conducted univariate logistic regression analysis to examine the effects of their length of stay and residential status on the prevalence of hypertension, diabetes, dyslipidemia, and obesity. In the final analysis, the result of each sex was adjusted for age, nationality, length of stay, and residential status via multiple logistic regression analysis. RESULTS: Longer length of stay tends to increase the prevalence of hypertension in male; 4-6 year stay-duration group demonstrated statistically significant excess compared to 1 year or less stay-duration group (adjusted odds ratio [OR], 1.39; confidence interval [CI], 1.01 to 1.92). After adjustment, male migrants stayed more than 7 year showed considerably higher dyslipidemia than male migrants stayed less than 1 year (adjusted OR, 1.95; CI, 1.05 to 3.64). Compared to the group with 1 year or less stay-duration, the prevalence of obesity in male was significantly higher among 4-6 year (adjusted OR, 1.65; CI, 1.17 to 2.32) and 7 year or more stay-duration group (adjusted OR, 1.65; CI, 1.11 to 2.45). CONCLUSION: Longer length of stay correlated to higher prevalence of hypertension, dyslipidemia, and obesity among some population of migrants. So more researches and new developing policies are needed for this problem.
