Using combined data from the population-based 2001 and 2003 California Health Interview Surveys, we examined ethnic and gender-specific smoking behaviors and the effect of three acculturation indicators on cigarette smoking behavior and quitting status among 8,192 Chinese, Filipino, South Asian, Japanese, Korean, and Vietnamese American men and women. After adjustment for potential confounders, current smoking prevalence was higher and the quit rate was lower for Korean, Filipino, and Vietnamese American men compared with Chinese American men. Women's current smoking prevalence was lower than men's in all six Asian American subgroups. South Asian and Korean American women reported lower quit rates than women from other ethnic subgroups. Asian American men who reported using only English at home had lower current smoking prevalence and higher quit rates, except for Filipino and South Asian American men. Asian American women who reported using only English at home had higher current smoking prevalence except for Japanese women. Being a second or later generation immigrant was associated with lower smoking prevalence among all Asian American subgroups of men. Less educated men and women had higher smoking prevalence and lower quit rates. In conclusion, both current smoking prevalence and quit rates vary distinctively across gender and ethnic subgroups among Asian Americans in California. Acculturation appears to increase the risk of cigarette smoking for Asian American women. Future tobacco-control programs should target at high-risk Asian American subgroups, defined by ethnicity, acculturation status, and gender.

The outbreak of coronavirus disease 2019 (COVID-19) has caused mental problems among the public and medical staff in China, especially for children and adolescents, a vulnerable group that might present with more mental problems. It seems that there is a rapid growth in the mental problems (such as depression or anxiety) of Chinese children and adolescents during the outbreak of COVID-19. Although several studies reported the prevalence of depression or anxiety problems for children and adolescents, the results are different across different age groups and sex groups. Moreover, the sample size of these studies was small. In the present study, we aim to perform a meta-analysis to identify the confirmed prevalence of depression and anxiety problems for Chinese children and adolescents during home confinement. Five databases were searched including PubMed, Web of Science, PsycINFO, Google Scholar, and the China National Knowledge Infrastructure (CNKI), and both inclusion and exclusion criteria were developed. Finally, a total of 12 studies were included in this meta-analysis. The protocol of this systematic review was registered with INPLASY (protocol ID: INPLASY202150032). It found that the pooled prevalence of mental problems was 28% (95% confidence interval, CI: 0.22–0.34), and the depression and anxiety problem for children and adolescents in China was 22% (95% CI: 0.16–0.30) and 25% (95% CI: 0.20–0.32) based on a random effect model, separately. Subgroup analysis was used to identify that there are no differences between different age groups (primary and middle school vs. high school) (p = 0.26). Meta-regression analysis was performed and the results showed that the moderator of boy percentage was a significant factor (p = 0.04). It indicated that there was an increasing number of children and adolescents with mental problems during the home confinement. It suggested that we should pay more attention to this vulnerable population during a public health crisis in the future, especially for the girls groups, and more detailed implements for mental health management were needed and should be prepared.Systematic Review: The protocol of this systematic review was registered with INPLASY. The protocol ID was INPLASY202150032

BackgroundThere are several mobile apps that offer tools for disease prevention and management among older adults, and promote health behaviors that could potentially reduce or delay the onset of disease. A classification scheme that categorizes apps could be useful to both older adult app users and app developers.ObjectiveThe objective of our study was to build and evaluate the effectiveness of a classification scheme that classifies mobile apps available for older adults in the “Health & Fitness” category of the iTunes App Store.MethodsWe constructed a classification scheme for mobile apps according to three dimensions: (1) the Precede-Proceed Model (PPM), which classifies mobile apps in terms of predisposing, enabling, and reinforcing factors for behavior change; (2) health care process, specifically prevention versus management of disease; and (3) health conditions, including physical health and mental health. Content analysis was conducted by the research team on health and fitness apps designed specifically for older adults, as well as those applicable to older adults, released during the months of June and August 2011 and August 2012. Face validity was assessed by a different group of individuals, who were not related to the study. A reliability analysis was conducted to confirm the accuracy of the coding scheme of the sample apps in this study.ResultsAfter applying sample inclusion and exclusion criteria, a total of 119 apps were included in the study sample, of which 26/119 (21.8%) were released in June 2011, 45/119 (37.8%) in August 2011, and 48/119 (40.3%) in August 2012. Face validity was determined by interviewing 11 people, who agreed that this scheme accurately reflected the nature of this application. The entire study sample was successfully coded, demonstrating satisfactory inter-rater reliability by two independent coders (95.8% initial concordance and 100% concordance after consensus was reached). The apps included in the study sample were more likely to be used for the management of disease than prevention of disease (109/119, 91.6% vs 15/119, 12.6%). More apps contributed to physical health rather than mental health (81/119, 68.1% vs 47/119, 39.5%). Enabling apps (114/119, 95.8%) were more common than reinforcing (20/119, 16.8%) or predisposing apps (10/119, 8.4%).ConclusionsThe findings, including face validity and inter-rater reliability, support the integrity of the proposed classification scheme for categorizing mobile apps for older adults in the “Health and Fitness” category available in the iTunes App Store. Using the proposed classification system, older adult app users would be better positioned to identify apps appropriate for their needs, and app developers would be able to obtain the distributions of available mobile apps for health-related concerns of older adults more easily.

Relationship between intestinal flora content and hypertension was investigated. Ninety-four patients with hypertension who were admitted and treated in No. 215 Hospital of Shaanxi Nuclear Industry from May 2016 to April 2017 were selected as the observation group; and 94 healthy people from the physical examination center of No. 215 Hospital of Shaanxi Nuclear Industry in the same time period were selected as the control group. The systolic (SBP) and diastolic blood pressure (DBP) of all the participants were measured. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to detect the quantities of Eubacterium rectale, Bacteroides thetaiotaomicron and Bifidobacterium in the intestines, and correlation analyses were performed. The SBP, DBP and content of Eubacterium rectale in the observation group were significantly higher than those in the control group, while the contents of Bacteroides thetaiotaomicron and Bifidobacterium were obviously lower than those in the control group (P<0.05). Pearson's correlation analysis showed that Eubacterium rectale was positively correlated with SBP and DBP, while Bacteroides thetaiotaomicron and Bifidobacterium had a negative correlation with SBP and DBP (P<0.05). The results showed that the quantities of Bifidobacterium and Bacteroides thetaiotaomicron are decreased while the number of Eubacterium rectale is increased in the intestines of patients with hypertension. Moreover, the content of intestinal flora has a significant correlation with hypertension.
