The Interaction between Exercise and Marital Status on Depression: A Cross-Sectional Study of the Taiwan Biobank.

Few studies evaluating the relationship between depression and exercise consider peoples' socio-demographic characteristics. This cross-sectional study investigated the interaction between exercise and marital status and depression in Taiwanese adults. Data from the 2-item Patient Health Questionnaire (PHQ-2) was recruited from the Taiwan Biobank. Participants indicated their exercise status, showing 5015 no-exercise cases and 3407 exercise cases. Marital status, including unmarried, divorced or separated, and widowed, were all significant, especially among the no-exercise group. The relationship between exercise/no exercise and marital status was examined; no exercise and unmarried, divorced or separated, and widowed, as well as exercise and married were significant to PHQ-2. Gender was significant in both the married and unmarried groups. The association between exercise, marital status, gender, and education on PHQ-2 score was also significant. Married people, especially men, had lower depression scores. Additionally, exercise had a protective effect against depression for unmarried people, especially women.

Association of Age and Sex with Metabolic Syndrome in Taiwanese Adults.

OBJECTIVE: This study aimed to investigate the association of age and sex with metabolic syndrome (MS) in Taiwanese adults. METHODS: We extracted information of 4307 men and 4783 women aged 30-70 from the Taiwan Biobank. RESULTS: The interaction between age and sex on MS was significant (p-value = 0.0001). After stratification by sex, men and women aged 50-70 years (reference: 30≤age<50 years) had a higher risk of MS. The odds ratio (OR), 95% confidence interval (CI) was 2.316, 1.936-2.772 in men and 3.101, 2.561-3.754 in women. After stratification by age, men aged 50-70 years had a lower risk of MS compared to women (OR, 95% CI = 0.713, 0.598-0.851). CONCLUSION: The interaction between age and sex on MS was significant. Sex-wise, both men and women aged 50-70 years had a higher likelihood of MS. Age-wise, men aged 50-70 years had a lower risk of MS compared to women.

APOE Variant (rs405509) might Modulate the Effect of Sex and Educational Level on Cognitive Impairment Risk in a Taiwanese Population.

Education, sex, and the APOE-rs405509 variant are associated with Alzheimer's disease and cognitive performance. We investigated if the rs405509 TT, TG, and GG genotypes modulate the effect of sex and education on cognitive impairment in Taiwanese adults. Data on cognitive health (defined by Mini-Mental State Examination (MMSE) scores) and rs405509 were from Taiwan Biobank. Participants included 2105 men and 2027 women with a mean age of 64 years. Education below university level was significantly associated with lower MMSE scores. The odds ratios (ORs) were 1.82; 95% confidence interval (CI) 1.38-2.41 for senior high school, 3.39; 95% CI 2.50-4.59 for junior high school, and 11.94; 95% CI 9.91-15.50 for elementary school and below (p-trend < 0.05). The association between MMSE score and sex was significant only in the lowest educational group (elementary and below), with lower odds of having a low MMSE score in men compared to women (OR = 0.51; 95% CI 0.34-0.77). After stratification by rs405509 genotypes, this association was significant only among TT genotype carriers (OR = 0.481; CI = 0.253-0.915). In conclusion, a significant association between MMSE score and sex was observed in the lowest educational group, especially among carriers of rs405509 TT genotypes.

Psychological well-being, dental esthetics, and psychosocial impacts in adolescent orthodontic patients: A prospective longitudinal study.

INTRODUCTION: We examined the role of adolescent orthodontic patients' psychological well-being attributes (self-esteem, general body image, and positive and negative affects) and the clinical indicators of dental esthetics (orthodontists' ratings on the Index of Orthodontic Treatment Need-Aesthetic Component [IOTN-AC]), and their changes from pretreatment to posttreatment as predictors of the psychosocial impact of dental esthetics. METHODS: In this prospective longitudinal study, 1090 adolescent orthodontic patients seeking treatment at the Stomatological Hospital of Chongqing Medical University in China (mean age, 14.25 years; SD, 2.03 years) were assessed before treatment, and 68.99% (n = 752) were assessed after treatment. All subjects completed a questionnaire measuring psychological well-being attributes and 3 components of the Psychosocial Impact of Dental Aesthetics (perceptive, cognitive-affective, and social-functional). Clinical indicators of dental esthetics were measured by 3 orthodontists using the IOTN-AC. RESULTS: Substantial enhancement from pretreatment to posttreatment was found in all 3 Psychosocial Impacts of Dental Aesthetics components, confirming the positive effects of orthodontic treatment on oral health-related quality of life. Psychosocial impact of dental esthetics at baseline and improvement from pretreatment to posttreatment were found to be predicted by the patients' psychological well-being attributes (self-esteem, general body image, and negative affect) and the clinical indicators (orthodontists' rating on the IOTN-AC) at baseline, as well as their pretreatment to posttreatment change. Psychological well-being attributes had comparable or greater contribution to the Psychosocial Impact of Dental Aesthetics at baseline as well as greater improvement after treatment than the clinical indicators. These biopsychological models explained 29% to 43% of the variances in psychosocial impacts of dental esthetics outcome at baseline and about 33% of the variance in pretreatment to posttreatment improvement. CONCLUSIONS: This study establishes a biopsychological model for understanding the psychosocial impact of dental esthetics and its improvement after orthodontic treatment among adolescent orthodontic patients. The findings highlight the importance of psychological parameters in orthodontic research and clinical practice.
