Association between fat-soluble vitamins and self-reported health status: a cross-sectional analysis of the MARK-AGE cohort.

ABSTRACT: Self-rated health (SRH) is associated with higher risk of death. Since low plasma levels of fat-soluble vitamins are related to mortality, we aimed to assess whether plasma concentrations of vitamins A, D and E were associated with SRH in the MARK-AGE study. We included 3158 participants (52 % female) aged between 35 and 75 years. Cross-sectional data were collected via questionnaires. An enzyme immunoassay quantified 25-hydroxyvitamin D and HPLC determined α-tocopherol and retinol plasma concentrations. The median 25-hydroxyvitamin D and retinol concentrations differed significantly (P < 0·001) between SRH categories and were lower in the combined fair/poor category v. the excellent, very good and good categories (25-hydroxvitamin D: 40·8 v. 51·9, 49·3, 46·7 nmol/l, respectively; retinol: 1·67 v. 1·75, 1·74, 1·70 µmol/l, respectively). Both vitamin D and retinol status were independently associated with fair/poor SRH in multiple regression analyses: adjusted OR (95 % CI) for the vitamin D insufficiency, deficiency and severe deficiency categories were 1·33 (1·06-1·68), 1·50 (1·17-1·93) and 1·83 (1·34-2·50), respectively; P = 0·015, P = 0·001 and P < 0·001, and for the second/third/fourth retinol quartiles: 1·44 (1·18-1·75), 1·57 (1·28-1·93) and 1·49 (1·20-1·84); all P < 0·001. No significant associations were reported for α-tocopherol quartiles. Lower vitamin A and D status emerged as independent markers for fair/poor SRH. Further insights into the long-term implications of these modifiable nutrients on health status are warranted.

Project description:OBJECTIVE:The attitudes of girls regarding menarche vary according to their cultural backgrounds. Asian girls may hesitate to discuss menarche. Computer-assisted self-administered interviewing (CASI) is considered a valid and effective tool for investigating the timing of menarche; however, the validity of self-reported menarche data from CASI in Chinese culture is currently unknown. We aimed to validate the status and age of menarche attainment by comparing CASI with face-to-face interviewing (FFI). METHODS:Based on a cross-sectional study, we collected information regarding the status and age of menarche attainment using CASI and FFI among Chinese schoolgirls. We explored the tools of standard epidemiological indices, including sensitivity, specificity, predictive values and accuracy to examine the capacity of CASI for correctly classifying the status of menarche. Both Pearson and Spearman correlations were calculated for the correlation of age at menarche using CASI with FFI. A Bland-Altman plot was drawn to measure the agreement between the two interview techniques. RESULTS:In this study, CASI and FFI were conducted in 3478 schoolgirls with an average age (SD) of 14.3 years (2.46). Menarche attainment was reported in 2496 (71.2%) and 2538 (73.0%) girls using CASI and FFI, respectively. Compared with FFI, the sensitivity, specificity, positive predictive value (PPV), negative predictive value and the accuracy of CASI were 0.97, 0.80, 0.96 and 0.92, respectively. The correlation of age at menarche between CASI and FFI was 0.728. Approximately >95%?and 76.3% of the difference in the age at menarche was within 12 months and 3 months, respectively, between the two interview methods. Among primary schoolgirls in grade 5, the sensitivity, specificity, PPV, accuracy and the correlation (0.335) of CASI was lower than those in other subgroups. CONCLUSIONS:Overall, the timing of menarche investigated using CASI was valid among all Chinese schoolgirls, except for those in grade 5 or lower.

Project description:Gingivitis and periodontitis are highly prevalent in Hong Kong, where the provision of oral health services is predominantly private. This cross-sectional study aimed to investigate the association between the oral symptoms of gum bleeding and self-reported behavioral factors, beliefs, and knowledge among Hong Kong Chinese. The research team commissioned the Public Opinion Programme of The University of Hong Kong to conduct a structured, population-based, computer-assisted telephone interview (CATI), which covered questions related to the demography, perception, and knowledge (including traditional Cantonese beliefs) of gum health, dental attendance, oral health behavior, and dental anxiety. A total of 1,265 individuals aged 25-60 years old were successfully contacted, and 704 (55.7%) reported prior gum bleeding experience. A total of 516 individuals (64.9% females, median 55-60 years) completed the CATI satisfactorily, and 321 (62.2%) experienced gum bleeding in the past 12 months. The factors that were significantly associated with reports of gum bleeding in the past 12 months include having periodontitis, sensitive teeth, having tertiary or higher education, flossing/interdental cleaning, not cleaning teeth well enough, lack of sleep, consuming too much 'heaty' food, avoiding going to the dentist when gums are bleeding, and waiting for gum bleeding to subside (p < 0.05, r2 =0.198; forward stepwise logistic regression). Within the limitations of this study, approximately half of the Hong Kong working-age adults surveyed reported experiencing gum bleeding, and 62.2% of the participants experienced it within the past 12 months. Members of Hong Kong's working-age population who reported having higher levels of education appeared more readily aware of their gum problems. Those with bleeding gums, especially those who have discernable periodontitis, poor dental awareness/behaviors, and/or a poor lifestyle should be targeted to receive education and encouragement, which will allow them to take action and improve their own gum health.
