Relationship Between Childhood Left-Behind Experience and Quality of Life Among Chinese University Freshmen: Place of Origin Matters

Elevated levels of loneliness in migrant children compared to nonmigrant children in urban China: a systematic review and meta-analysis of comparative studies

PURPOSE OF REVIEW

About one in four children in China is a migrant child. This population has a higher risk of experiencing loneliness. However, existing studies present conflicting findings regarding the levels of loneliness among migrant children as compared to local urban children in urban China. This review performs a meta-analysis of studies comparing loneliness levels between these two groups.

RECENT FINDINGS

A literature search of major Chinese- and English-language databases revealed 27 eligible comparative studies. These studies reported the means and standardized deviations of loneliness scores for both migrant and nonmigrant children in urban China. Meta-analysis results showed that migrant children experienced significantly higher levels of loneliness than their urban nonmigrant counterparts [standardized mean difference (SMD) = 0.21, P  < 0.001]. Subgroup analysis revealed that studies enrolling migrant children from migrant children's schools had significantly higher pooled SMDs than those enrolling children from public schools (0.346 vs. 0.120, P  = 0.047).

SUMMARY

Migrant children in urban China experience higher levels of loneliness compared to their local urban peers. Efforts to create a socially inclusive, migrant-friendly environment and reduce social isolation among migrant children are crucial to help alleviate their feelings of loneliness.

Relationship between left-behind status and cognitive function in older Chinese adults: a prospective 3-year cohort study

Background

Due to the inaccuracy of the traditional geographical distance-based definition of left-behind status, data on the negative effect of left-behind status on cognitive function among older adults are controversial.

Aims

This study examined the cross-sectional and longitudinal associations of left-behind status with cognitive function in older Chinese adults. The left-behind status definition was based on the frequency of face-to-face parent-child meetings.

Methods

Data from a nationally representative sample of 8 682 older adults (60+ years) in 2015 (5 658 left behind and 3 024 non-left behind), of which 6 933 completed the follow-up in 2018, were obtained from the China Health and Retirement Longitudinal Study. Left-behind older adults were broadly defined as those aged 60+ years who had living adult children and saw their children less than once per month. The cognitive function was assessed with a composite cognitive test with higher total scores indicating better cognitive function.

Results

Left-behind older adults had significantly lower cognitive test scores than non-left-behind older adults in both 2015 (11.1 (6.0) vs 13.2 (5.9), t=15.863, p<0.001) and 2018 (10.0 (6.6) vs 12.4 (6.7), t=14.177, p<0.001). After adjusting for demographic factors, lifestyle factors, chronic medical conditions and the baseline cognitive test score (in the longitudinal analysis only), on average, the cognitive test score of left-behind older adults was 0.628 lower than their non-left-behind counterparts in 2015 (t=5.689, p<0.001). This difference in cognitive test scores attenuated to 0.322 but remained significant in 2018 (t=2.733, p=0.006).

Conclusions

Left-behind older Chinese adults have a higher risk of poor cognitive function and cognitive decline than their non-left-behind counterparts. Specific efforts targeting left-behind older adults, such as encouraging adult children to visit their parents more regularly, are warranted to maintain or delay the progression of cognitive decline.

Sleep disturbance and quality of life among university freshmen in Qinghai-Tibet Plateau of China

PURPOSE

University freshmen are particularly vulnerable as they are undergoing the transition from high school to university with a range of changes. Sleep problems among this group in the Qinghai-Tibet Plateau of China were barely studied. This study aimed to explore sleep disturbance, and its association with quality of life (QoL) and demographic and clinical characteristics among university freshmen in Qinghai-Tibet Plateau, China.

METHODS

A multistage stratified cluster random sampling method was performed to recruit student participants with a structured questionnaire to collect sociodemographic and clinical characteristics, and lifestyle behaviors. Sleep disturbance including three aspects of sleep disturbance (i.e., difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), and early morning awakening (EMA)) was assessed using standardized measurement. Multiple logistic regression models were applied to analyze the data.

RESULTS

Among included 2,769 freshmen, the prevalence of sleep disturbance was 14.8% (95% CI: 14.2-15.5%), and corresponding prevalence of DIS, DMS, and EMA was 8.2% (95% CI: 7.7-8.7%), 8.3% (95% CI: 7.8-8.8%), and 4.2% (95% CI: 3.8-4.6%), respectively. Freshmen with sleeping disturbance had significantly lower QoL in physical [F _{(1, 2769)} = 60.23, p < 0.001], psychological [F _{(1, 2769)} = 46.18, p < 0.001], social [F _{(1, 2769)} = 23.04, p < 0.001], and environment [F _{(1, 2769)} = 6.07, p = 0.01] domains. Multiple logistic regression analyses revealed that having breakfast five times a week or less (less than three times, OR = 1.79, 95% CI: 1.34-2.40; 3-5 times, OR = 1.40, 95% CI: 1.09-1.79), self-perceived severe Internet dependence (OR = 1.71, 95% CI: 1.11-2.65), self-perceived poor health status (OR = 3.44, 95% CI: 2.06-5.74), high academic stress (OR = 1.42, 95% CI: 1.13-1.78), poor relationship with classmates (OR = 3.44, 95% CI: 1.53-7.71), and severe ADHD symptoms (OR = 1.08, 95% CI: 1.05-1.12) were positively associated with sleeping disturbance.

CONCLUSION

Sleep disturbance was common among freshmen and is associated with poorer QoL. Prevention and intervention strategies should be developed and implemented, especially among the vulnerable university freshman groups.
