National and Subnational Trends in Mortality and Causes of Death in Chinese Children and Adolescents Aged 5-19 Years From 1953 to 2016

Trends in mortality and causes of death among Chinese adolescents aged 10-19 years from 1990 to 2019

Objective

Promoting adolescent health is essential to achieving the goals of the Healthy China 2030 (HC 2030) initiative. As socioeconomic conditions improve and medical practices and disease patterns evolve, adolescent mortality rates and causes of death vary considerably. This study provides up-to-date data on adolescent mortality and causes of death in China, highlighting key areas of focus for investment in adolescent health.

Methods

Data regarding mortality and causes of death in Chinese adolescents aged 10-19 years were extracted from the Global Burden of Disease study from 1990 to 2019. The data variables were examined according to year, sex, and age. The autoregressive integrated moving average model was used to predict non-communicable disease (NCD) mortality rates and rank changes in the leading causes of death until 2030.

Results

The all-cause mortality rate (per 100,000 population) of Chinese adolescents aged 10-19 years steadily declined from 1990 (72.6/100,000) to 2019 (28.8). Male adolescents had a higher mortality (37.5/100,000 vs. 18.6 in 2019) and a slower decline rate (percent: -58.7 vs. -65.0) than female adolescents. Regarding age, compared with those aged 10-14 years, the mortality rate of adolescents aged 15-19 years had a higher mortality (35.9/100,000 vs. 21.2 in 2019) and a slower decrease rate (percent: -57.6 vs. -63.2). From 1990 to 2019, the rates of communicable, maternal, and nutritional diseases declined the most (percent: -80.0), while injury and NCDs mortality rates were relatively slow (percent: -50.0 and -60.0). In 2019, the five leading causes of death were road injuries (6.1/100,000), drowning (4.5), self-harm (1.9), leukemia (1.9), and congenital birth defects (1.3). Furthermore, NCDs' mortality rate decreased by -46.6% and -45.4% between 2015-2030 and 2016-2030, respectively.

Conclusion

A notable decline was observed in all-cause mortality rates among Chinese adolescents aged 10-19 years. In addition, the mortality rates of NCDs are projected to meet the target from the Global Strategy for Women's, Children's, and Adolescents' Health (2016-2030) and HC2030 reduction indicators by 2030. However, it should be noted that injury is the leading cause of death, with sexual and age disparities remaining consistent.

Context of boat drowning in Ghana: a mixed qualitative research study

BACKGROUND

Drowning is a significant public health challenge globally. In Africa and Ghana, drowning has remained a silent epidemic among poor communities. Limited evidence has challenged advances in drowning knowledge and prevention. While drowning deaths are often widely circulated in the newspapers, drowning data are not systematically organised to constitute a body of evidence sufficient for scientific exploration. Although drowning was frequent, they were poorly understood. We explore the context of drowning from multiple perspectives from the Volta-basin where the largest man-made lake in the world has become a hotspot for drowning.

METHOD

This study adopts a sequential-mix-qualitative study comprising content analysis of newspaper reports on drowning, structured-observations and in-depth interviews with boaters and fisherfolk. We first explored, the content of newspapers over a 10-year period. This information provided the context of drowning. We followed up with extensive observation of activities on the lake by a team of five. Photovoice qualitative interviews were conducted with 22 boaters, fishers and community members. Thematic content analysis was applied to both the newspaper reports and the in-depth interviews.

RESULTS

Drowning was attributed to both proximate and distal causes. Distal causes were the reasons for movement, while proximate causes were the immediate cause of the drowning. Travelling to farm, market, hospital, church, sell were important distal causes of drowning. Proximate determinants included strong winds, tree stumps, overcrowding, no-adherence to safety procedures, spiritual reasons and high tides. Four types of boat accidents were observed: boat-capsizing, boat-sinking, boat-splitting and boat-catching-fire. Ideas converged and diverged in comparing the newspaper content analysis to the photovoice interviews.

Translation and validation of the STARx questionnaire in transitioning Chinese adolescents and young adults with chronic health conditions

BACKGROUND

Adolescent/young adults (AYAs) with chronic conditions must undergo healthcare transition (HCT) preparation until their mid-twenties. Valid HCT readiness measures are lacking in China.

METHODS

The present study translated, back-translated, and adapted the Self-Management and Transition to Adulthood with Rx = Treatment (STAR_x) Questionnaire. We examined the psychometric properties of this tool in a relatively large in-patient sample of AYAs with various chronic health conditions at a Chinese tertiary general hospital.

RESULTS

We enrolled 624 AYAs aged 10-25 years (19.66 ± 3.64) with various chronic health conditions. The Chinese version of the STAR_x Questionnaire demonstrated excellent internal consistency (Cronbach's alpha = 0.83) and reliability with a two-week test-retest (ICC = 0.88, p < .001). Furthermore, the Chinese version revealed a three-factor structure (self-management, disease knowledge, and provider communication) consistent with the revised English version of the STAR_x Questionnaire. In terms of discriminant validity, the total score of the Chinese STAR_x Questionnaire showed a significant positive correlation with age but no gender differences were found. In terms of predictive validity, the Chinese STAR_x Questionnaire was significantly correlated with shorter length of hospitalization and higher frequency of emergency room visit, but the correlations became insignificant after controlling for age.

CONCLUSIONS

The results suggest that the Chinese version of the STAR_x Questionnaire is a robust HCT readiness tool in AYAs with chronic conditions and clinicians may find it useful to develop individualized interventions.

Maintenance mechanisms of child restraint system use based on the health action process approach theory: Evidence from China

OBJECTIVE

Adherence to the use of child restraint system (CRS) can greatly reduce child casualties in road traffic accidents. This study aims to develop the behavior maintenance model of CRS use based on the health action process approach (HAPA) theory to explore the maintenance mechanisms, suggesting appropriate intervention strategies.

METHODS

Adopting the multi-stage stratified cluster random sampling method, a cross-sectional survey for guardians recruited from kindergarten and primary school was conducted using the questionnaire developed based on the HAPA theory in Nanjing, China, and 1135 valid samples were finally obtained. Rigorous analysis procedures of the partial least squares structural equation modeling (PLS-SEM) method were applied by using SmartPLS3.3.2 software.

RESULTS

The results confirmed that action self-efficacy (β = 0.479, P < 0.001) and negative outcome expectancy (β = -0.187, P < 0.001) were valid predictors of intention in the non-intentional stage, intention (β = 0.488, P < 0.001) and maintenance self-efficacy (β = 0.334, P < 0.001) contributed significantly to action planning in the intentional stage, while action planning (β = 0.470, P < 0.001) and recovery self-efficacy (β = 0.256, P < 0.001) jointly determined behavior maintenance in the action stage. It was also revealed that action planning fully mediated the relation between intention and behavior maintenance (β = 0.229, P < 0.001).

CONCLUSION

Based on the above mechanisms, interventions aimed at the stages of non-intention, intention, and action should be designed and implemented, with the participation of the government, automobile dealers, and communities to promote the maintenance of improved CRS use behavior.

National and sub-national levels and causes of mortality among 5-19-year-olds in China in 2004-2019: A systematic analysis of evidence from the Disease Surveillance Points System

Background

China accounts for 13% of the world’s 5-19-year-olds population. We estimated levels and trends of mortality by sex-age-cause among 5-19-year-olds at national and subnational levels in China annually from 2004 to 2019, to inform strategies for reducing child and adolescent mortality in China and other countries.

Methods

We used adjusted empirical data on levels and causes of deaths from the China Center for Disease Control and Prevention’s Disease Surveillance Point (DSP) system. We considered underreporting and surveillance sampling design, applied smoothing techniques to produce reliable time trends, and fitted age-specific deaths and population to national estimates produced by international agencies to allow for cross-national comparisons.

Results

The top leading causes for 54 594 deaths among 5-19-year-olds were neoplasms, road traffic injuries, and drowning. All-cause mortality in 5-19-year-olds has been declining steadily between 2004-2019, with evident yet narrowing geographical and gender disparities. Injury mortalities were one of the fastest declining causes, but widespread disparities were observed across subpopulations. Falling injuries and rising non-communicable diseases had the most pronounced epidemiological transition in the eastern region. Decrease in drowning fractions stalled for 15-19-year-olds in central/western rural areas. Suicide shares sustained or increased for 15-19-year-olds except among females in eastern rural areas.

Conclusions

China made significant improvements in child and adolescent survival since 2004. However, constant targeted investments are needed to maintain and accelerate progress. A sustainable sample registration system like the DSP is likely essential for supporting such a process.
