ABSTRACT
Objective@#To evaluate the impact of sugar sweetened beverages (SSBs) tax on childhood obesity by literatures reveiew, and to provide evidence support for childhood obesity prevention and control strategies in China.@*Methods@#A systematic review method was used to search relevant literatures published to November 30，2020 from 8 databases including CNKI, VIP, Wanfang Data, PubMed, Medline, SpringerLink, Web of Science, and Science Direct. The high quality system reviews published since 2016 were included directly, and those published before 2016 were rereviewed before combined with other literatures.@*Results@#Twelve studies including 5 systematic reviews (or Meta analysis), 1 cohort study and 6 cross sectional studies were included. Comprehensive analysis showed that the prevention effect on childhood obesity was small or even ineffective if the tax on SSBs lower than 5%, a certain protective effect on childhood obesity could be shown if the tax on SSBs increased to 20%. From the perspective of cost benefit analysis, the implementation of SSBs tax showed certain net benefits.@*Conclusion@#SSBs tax can help reduce the risk of childhood obesity.
ABSTRACT
OBJECTIVE@#To explore the direct relationship between personality (PN) and sub-health status (SHS) and their indirect association mediated by frustration quotient (FQ) and stress event (SE).@*METHODS@#A multiple-stage stratified sampling method was used to choose the participants, and a total of 4517 eligible urban residents were selected.ANCOVA was used to analyze the independent association between personality and SHS after adjusting the demographic characteristics and lifestyle.A structural equation model was used to analyze the associations among personality, FQ, SE and SHS.Bootstrap method was used to test the direct and indirect association between personality and SHS.@*RESULTS@#Personality was independently associated with total sub-health (=75.913, < 0.001), physical sub-health (=23.618, < 0.001), mental sub-health (=101.993, < 0.001) and social sub-health (=48.757, < 0.001).The urban residents with the personalities characterized by anger suppression, anxiety and irritability, and impatience and competitiveness had significantly lower health scores than those with a mature and steady personality ( < 0.05).Personality was associated with FQ and SE, and the indirect association between personality and physical sub-health was mainly mediated by FQ and SE (β=-0.110).Personality showed more a direct association (β=-0.172) with mental sub-health and a slightly less indirect association (β=-0.126) with mental sub-health.Personality showed a more indirect association (β=-0.113) with social SHS and slightly less direct association (β=-0.082) with social sub-health.@*CONCLUSIONS@#A mature and steady personality may help to promote the general health level, while the personalities of anger suppression, anxiety and irritability, impatience and competitiveness can be associated with the occurrence of sub-health.Building a mature and steady personality has positive effects on the health in general of an individual.

OBJECTIVE@#To establish the norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents.@*METHODS@#Using a multistage stratified sampling method, we conducted a large-scale epidemiological investigation among 15 066 urban residents sampled from 6 regions in China, including Tianjin City (north China), Guangdong Province (south China), Anhui Province (central south China), Sichuan Province (southwest China), Lanzhou City (northwest China) and Harbin City (northeast China). The mean, percentile and threshold norms were established based on the characteristics of SHMS V1.0 scores for Chinese urban residents.@*RESULTS@#The mean and percentile norms of total, physical, mental and social sub-health of Chinese urban residents were established according to gender and different age groups (14-19, 20-29, 30-49, 50-64 and ≥65 years). The threshold norms of SHMS V1.0 divided 5 health states, namely disease, severe sub-health, moderate subhealth, mild sub-health and healthy states according to the ± and ±0.5 of the converted scores.@*CONCLUSIONS@#The norms of Sub-Health Measurement Scale (SHMS V1.0) for Chinese urban residents were established, which provides a reference for rapid screening and diagnosis of sub-health status in Chinese urban residents and facilitates further study of the prevalence and contributing factors of sub-health.
