Aging and separation from children: The health implications of adult migration for elderly parents in rural China

Complex nexus: Economic development, rural-to-urban migration, and transition to adulthood in China

Transition to adulthood in low- and middle-come countries (LMIC) has increasingly been diversified and individualized. Economic development and migration are often cited as reasons for diversification but have been analytically examined interactively. To examine the complex linkages between development, migration, and transition to adulthood, we use China data to cover a decade when it has experienced rapid economic development, a large flow of rural-to-urban migration, and changes in the transition to adulthood. Applying the latent class analysis and multinomial logistic regression on the Chinese General Social Survey 2008 and 2017, we obtain three main findings. First, economic development increases the diversification of the transition to adulthood. Second, rural-to-urban migration has a greater impact on the postponement than on other pathways. Third, the joint impact of economic development and migration is not evident: the change do not differ between men and women as well as young adults of different migration experience. These findings collectively imply signs of the diversification of transition to adulthood in China, but also entail the individualization behind it.

Nutritional status of children left behind by migrant parents: Evidence from a survey in rural Anhui, eastern China

We aimed to explore and analyse the dietary intake patterns of 3-6 year-old children left behind by one or both parents and to assess their associations with body mass index (BMI) and the prevalence of childhood anaemia in rural Anhui, eastern China. We used random cluster sampling to recruit rural children aged 3-6 years in two rural areas in Anhui province. Sociodemographic information and dietary intake were collected by self-reported questionnaires. Height, weight and prevalence of anaemia were measured by trained nurses blinded to parental migration status. Factor analysis was applied to determine that major dietary patterns, binary logistic regression and generalised linear regression were used to explore the associations between anaemia and BMI Z-score with dietary patterns. Of 1720 children aged 3-6 years, 236 were left by both parents and 388 were left by a single parent. The prevalence of stunting and underweight among left-behind children with migration of both parents (BLBC) was significantly higher than that of non-left-behind children (NLBC). Three dietary patterns-"grain-vegetable," "meat-egg" and "fast food-sweet"-were identified in our study, and the total variance explained was 46.9%. The meat-egg dietary pattern was associated with a decreased risk of anaemia after adjustment for confounding factors in the left-behind children with migration of both parents (BLBC), left-behind children with single parent migration (SLBC) and non-left-behind children (NLBC) groups. After adjusting for confounding factors, the fast food-sweet dietary pattern was found to be associated with an increased risk of anaemia (OR [95% CI]: Q4: 2.21 [1.14, 4.57], p = 0.034). In addition, children with obesity had a lower intake of vegetables and fruits (β = -0.08, 95% CI: -0.13, -0.02) compared with children with a normal weight. In conclusion, there are correlations between different types of parental migration and children's nutritional status in rural Anhui. The meat-egg dietary pattern may have a preventive effect on anaemia in comparison with other dietary patterns, irrespective of whether children are left behind or not. Children with overweight and obesity had a higher intake of pork and red meat and snacks compared with children with normal BMI.

Associations Between Self-Reported Visual Difficulty, Age of Onset, and Cognitive Function Trajectories Among Chinese Older Adults

Objectives: This study examined the association between self-reported visual difficulty and age-related cognitive declines among older Chinese adults and how the timing of visual difficulty onset plays a role in cognitive trajectories. Methods: Data were drawn from the 2011-2018 wave of the China Health and Retirement Longitudinal Study, involving 9974 respondents aged 60 years or older (mean age 65.44 years, range 60-101 years). Results: At baseline, 14.16% respondents had self-reported visual difficulty. Growth curve models showed that Chinese older adults with visual difficulty experienced a faster decline in cognitive function compared to those without visual difficulty (β = -0.02, p < .01). Older adults who began experiencing visual difficulty between 61 and 75 years of age had steeper cognitive declines compared to those with earlier or later onset (β = -0.05, p < .01). Discussion: Older adults with self-reported visual difficulty experience faster rates of cognitive decline. Future research should explore potential factors that underlie the association between onset timing of visual difficulty and cognitive function.

The Impact of Informal Care on Healthcare Utilization of Older Adults with Functional Limitations in China

Our study examines the impact of informal care on healthcare utilization, focusing on caregiver types, urban-rural, and gender differences. Analyzing data from the China Health and Retirement Longitudinal Study and using fixed effects models, we discovered complementary effects between informal care and healthcare. Specifically, spousal care increased inpatient care use, adult child care boosted both inpatient and outpatient use, and dual care from children and spouses showed the most significant impact on healthcare use. The association between informal care and healthcare use varied across gender or urban-rural residence. Our findings highlight the importance of caregivers in accessing healthcare services.

Early stimulation and responsive care: A mediator of caregivers' depression on the suspected developmental delay of left-behind children in China

BACKGROUND

Due to multiple factors, left-behind children in rural areas suffer from neurodevelopment delay and their caregivers suffer from depressive symptoms. This study aimed to analyze the effect of caregivers' depressive symptoms on left-behind children's neurodevelopment, with early stimulation and responsive care mediating.

METHODS

We conducted a cross-sectional survey in five counties in China. A total of 904 left-behind children aged 0-3 and their primary caregivers were enrolled. The Zung Self-rating Depression Scale (ZSDS) was used to measure caregivers' depressive symptoms. The Ages and Stages questionnaires-third edition (ASQ-3), which contains five domains: communication (CM), gross motor (GM), fine motor (FM), problem-solving (CG), and personal social (PS), was used to screen children for suspected developmental delay (SDD).

RESULTS

31.4 % of left-behind children suffered from SDD, while 39.7 % of left-behind children's caregivers experienced depressive symptoms. Caregivers' ZSDS scores were positively correlated with the SDD on four domains (FM, GM, CG, and PS), while Early stimulation and responsive care was negatively correlated with the SDD on four domains (CM, FM, CG, and PS).

LIMITATIONS

The cross-sectional design limited the ability to ascertain causal relations. Besides, the findings may not be generalized to all regions of China due to the heterogeneity of the study population.

CONCLUSIONS

Left-behind children under three years old in rural China were at high risk of SDD, while a substantial proportion of their caregivers had depressive symptoms. Caregivers' depressive symptoms may negatively affect the SDD of left-behind children through caregivers providing less early stimulation and responsive care.

Social capital and well-being of the elderly 'left-behind' by their migrant children in India

BACKGROUND

The study aims to examine the association between individual forms of social capital and the well-being of the elderly 'left-behind' parents and to determine if there is a gender difference within the possible relationship.

METHODS

This study applied the first wave of the Longitudinal Ageing Study in India (LASI, 2017-18) data. In this study, the respondents were 4,736 older parents 'left-behind' by their migrant adult sons. We employed descriptive statistics and bivariate analysis to assess the study sample's characteristics. The proportion test was performed to examine if there was a significant gender difference among older adults regarding depression, ADL, and IADL impairments. In addition, binary logistic regression was utilized to investigate the associations between social capital and elderly parents' health outcomes.

RESULTS

This study found a significant gender difference in depression (male: 8.26%; female:11.32%; P < 0.001), ADL (male:20.23%; female:25.75%; P = 0.032), and IADL (male: 33.97% female: 54.13%; P < 0.001) limitations. Elderly parents who did not participate in any social activity had a higher odd of ADL (aOR: 2.44; 95%CI: 1.882-3.171; P = < 0.001) and IADL (aOR: 1.22; 95%CI: 1.034-1.766 ; P = < 0.001) limitations. Networking with friends through phone/email conversations has a substantial impact on lowering depression in older parents. Older adults with good personal social capital were less likely to have depression, ADL, and IADL limitations.

CONCLUSION

Personal social capital is closely associated with the well-being of left-behind older parents. More efforts should be in place to increase the stock of social capital in this group with focused gender disparity.

Existing Datasets to Study the Impact of Internal Migration on Caregiving Arrangements among Older Adults in China

Massive rural-to-urban migration in China has a significant impact on informal caregiving arrangements among Chinese older adults. To stimulate research on the intersection of migration and caregiving, we conducted an inventory of longitudinal aging survey datasets from mainland China. Large publicly available datasets that included measures related to migration and caregiving were searched and reviewed for eligibility. Key characteristics of each dataset, including study design, sample size, and measures, were extracted. Seven eligible datasets were identified, and five included nationally representative samples. Measures for migration varied across datasets. Some datasets included information on the migration history of older adults, whereas others focused on the migration of adult children. Similarly, caregiving was measured using different questions in each dataset. Caregiving activities were assessed with regard to their type, source, and amount. High-quality datasets exist to support research on migration and caregiving arrangements among Chinese older adults.

Forced migration-induced diminished social networks and support, and its impact on the emotional wellbeing of older refugees in Western countries: A scoping review

As the number of refugees continues to increase globally, so does the number of older adults forced to migrate from their home region to Western countries. Many of these older refugees lose their social networks and support to the events leading to forced migration and may be unable to recreate them once resettled. We used Arksey and O'Malley's (2005) framework to explore how forced migration has diminished the social networks and support of older refugees in Western countries and its impact on their emotional well-being. Eight databases were searched for the review; abstracts were reviewed using Rayyan QCRi(c) before the full-text review. A total of 25 studies were included in the final analysis, and findings revealed that forced migration reduced the quantity of social networks and the quality of social support older refugees received. The reduced social network and support led to social isolation, increased migration-related grief, and mental health challenges. Advances in digital technology are not yet capable of filling the support gap. With this, we hope to inform future research on the social support needs of older refugees and raise awareness of the need for humanitarian support intervention to cushion the impact of the migration-induced loss of social networks and support.

Separated kin: location of multiple children and mental health trajectories of older parents in rural China

OBJECTIVE

This study examines the longitudinal association between the location of multiple children and depressive symptoms of older parents in rural China, where massive rural-to-urban migration has profoundly altered the family life of the aging population.

METHODS

Using seven waves of panel data from the Longitudinal Study of Older Adults in Anhui Province (2001-2018, N = 8,253) and multilevel growth curve models, this study compares mental health trajectories of old parents across different compositions of local and migrant children over an 18-year time period.

RESULTS

The results show that older parents with a greater share of adult children who had migrated away not only scored worse mental health on average, but also experienced a more rapid increase in depressive symptoms across ages, after accounting for other covariates. Further, older adults who had their most children migrated away for a longer period of time suffered from the steeper rate of increase in depressive symptoms as they got older.

CONCLUSIONS

We suggest that it is not the geographic locality of a single child but the location of multiple children that matters for parental mental health in later life.

By Internal Network or by External Network?-Study on the Social Network Mechanism of Reducing the Perception of Old-Age Support Risks of Rural Elders in China

Nowadays, it is a general trend for China to enter a deep aging society, and the aging situation of the rural population is particularly severe. As informal endogenous resources in rural areas, social networks play an essential role in ensuring elders' later life. Data were drawn from a questionnaire survey of 1126 rural elders in 11 provinces of China. Descriptive statistics and an ordinary least square regression model were conducted to explore the impact of social networks on the perception of old-age support risks of rural elders. There was a significant positive association between the social network size and the reduction in perception of old-age support risks of rural elders. The reduction effect was mainly reflected in the internal network size, whereas it was not evident in the external network size. There was a significant positive association between the heterogeneity of the network and the perceived level of old-age support risks of rural elders. There was a significant positive association between the communication frequency of external network relationships and the perceived level of old-age support risks of rural elders. We found a significant negative association between the ratio of communication frequency between the internal and external network relationships and the perception of old-age support risks of rural elders. Compared with the external network, the internal network had a more evident reduction effect on the social network mechanism of perception of old-age support risks of rural elders.

The impact of adult children rural-urban migration on left-behind parents' health: Evidence from China

Population aging and rural-urban migration have posed challenges to the elderly support system in developing countries that lack social safety net and services. Given that there is no consistent conclusion in the literature on whether adult children's internal migration can improve or impair their left-behind parents' health, little is known about the effect mechanisms. This paper investigates the comprehensive impact of adult children's migration on the health of their parents in rural China by analyzing the income effect and time allocation effect. The empirical analysis uses the rural sample of the China Health and Retirement Longitudinal Study (CHARLS) in 2013, 2015, and 2018. We found that adult children migration can improve parents' physical health, mainly thanks to the income effect. The analysis of the mechanism found that although the income effect has a positive effect on parents' health, the time allocation effect has a negative effect on parents' health because of the lack of care and increased working hours of parents. Our findings suggest that providing social care services and enhancing intergenerational communication can be practical strategies to mitigate the negative effect of children's migration to rural left-behind elderly parents.

Drinking water behavior and willingness to use filters by middle-aged and elderly residents in rural areas: A cross-sectional study in Tengchong, China

Access to safe drinking water is critical to health and development issues, and residents' drinking behavior reflects their awareness of health and water hygiene. Random sampling and face-to-face questionnaires were used to investigate the drinking water behavior, sanitation and perceptions of drinking water among middle-aged and elderly residents in Tengchong, southwest Yunnan from July 1 to July 28, 2021. Differences between groups were assessed using the Chi-square test and t-test. Two binary logistic regression analyses were conducted to explore the influencing factors of drinking unboiled tap water and willingness to use filters. Results show that 35% of residents drink unboiled tap water, and 29.8% of respondents indicated a willingness to use filters. The model results showed a strong correlation between 60 and 79 years old (OR: 0.510, 95% CI: 0.303-0.858), 80 and above years old (OR: 0.118, 95% CI: 0.038-0.365), drinking water at a regular interval (OR: 0.397, 95% CI: 0.257-0.612), wanting to gain knowledge about drinking water (OR: 0.198, 95% CI: 0.099-0.395), Perceived health risks (PHR) (OR: 0.847, 95% CI: 0.771-0.929), having kidney stones (OR: 2.975, 95% CI: 1.708-5.253) and drinking unboiled tap water (p < 0.05). 60-79 years old (OR: 0.446, 95% CI: 0.244-0.815), 80 and above years old (OR: 0.228, 95% CI: 0.064-0.812), water storage (OR: 0.088, 95% CI: 0.026-0.300), middle school and above (OR: 2.238, 95% CI: 1.289-3.883), household water treatment (HWT) (OR: 33.704, 95% CI: 9.726-116.791), Perceived health risks (PHR) (OR:1.106, 95% CI: 1.009-1.213), water authority satisfaction (WAT) (OR:0.857, 95% CI: 0.769-0.956) and willingness to use filters were correlated (p < 0.05). Our findings suggested that a certain proportion of permanent middle-aged and elderly residents in rural areas still drink unboiled tap water, and residents are less willing to use filters. Residents' perception of drinking water can reflect residents' drinking water behavior and willingness to a certain extent. It is recommended that the government and Centers for Disease Control (CDC) should strengthen relevant measures such as knowledge popularization and health education, and regulate the water use behavior of middle-aged and elderly residents. Promote safe, economical and effective household water filtration facilities to ensure public health safety.

Psychometric properties of the Persian version of the "Intergenerational relationship quality scale for aging parents and their children"

BACKGROUND

Investigating the status of intergenerational relationships of elderly parents with their adult childen is very important in examining issues related to the status of the elderly such as well being and quality of life and other aspects of elderly life. Giveeen the significance of the topic, the current study aimed to examine the psychometric properties of the Persian version of "Intergenerational Relationship Quality Scale for Aging Parents and Their Children" (IRQS-AP).

MATERIALS AND METHODS

A total of 463 community-dwelling elders (aged 60 years or older) in Tehran participated in this study through multistage cluster sampling method. To investigate reliability, the construct and convergent validity of the IRQS-AP, confirmatory factor analysis (CFA), and interclass correlation coefficient were done.

RESULTS

The content validity index was 0.84 for the entire tool. In the CFA, we found the instrument had a four-factor structure and adequate internal consistency. The scale had a significant and positive correlation with the two measures of loneliness and depression. Furthermore, Cronbach's alpha was estimated at 0.77, and the high value of the interclass correlation was 0.82.

CONCLUSION

The IRQS-AP is a valid and reliable scale that can be used to examine the status of intergenerational relationship quality in Iranian elder population.

Migration of adult male children and associated depression among community-dwelling older parents: A cross-sectional gender analysis from Longitudinal Ageing Study in India, 2017-2018

OBJECTIVES

This study empirically examines the association of migration of an adult male child (ren) on the mental health of the older parents left behind. It also examines the interaction effects of sex of older parents and male child migration on major depression to explore whether there is a gender differential in the possible association.

METHODS

The data for this study were obtained from the first wave of the Longitudinal Ageing Study in India (LASI, 2017-2018). The total sample size for the present study was 27,248 older adults aged 60 years and above (male-12,624; female-14,624). Descriptive statistics along with cross-tabulation were presented. Proportion test was used to evaluate the significance level of differences in depression by sex. Additionally, binary logistic regression analysis was used to find out the associations. Major depression with symptoms of dysphoria, was calculated using the Short-Form Composite International Diagnostic Interview (CIDI-SF).

RESULTS

About 10.5% and 9.0% of older males and females had migrant sons. It was found that there was significant gender differential in depression in older age (male: 7.5% and female: 9.7%; p < 0.001). It was further found that the prevalence of depression was found among older men (9.3% vs. 7.3%) and women (12.5% vs. 9.4%) with migrant son. Older adults with migrant son had 26% significantly higher likelihood to be depressed in reference to older adults with non-migrant son (AOR: 1.26; CI: 1.02-1.56). Further, older women with a migrant son had 76% significantly higher likelihood to be depressed in reference to older men with migrant son (AOR: 1.76; CI: 1.32-2.39).

CONCLUSIONS

This study invites policymakers' attention towards migration of adult children and its potential effects on mental health of left-behind older parents in community-settings and in women in particular. Policies should focus on spreading awareness to migrant children of older adults on maintaining frequent contacts and visits to their ageing parents.

Impact of child's migration on health status and health care utilization of older parents with chronic diseases left behind in China

BACKGROUND

Adult child are used to taking the responsibility of taking care of their older parents in Chinese culture. However, the migration of adult child is not uncommon now in the context of urbanization in China. The purpose of this study is to explore the impact of child's migration on health status and health care utilization of older parents with chronic diseases left behind.

METHODS

The data of the 2015 nationally representative longitudinal survey of the aged population in China were used in this study. Binary logistic regression was used to evaluate the impact of adult child's migration on health status and health care utilization of older parents with chronic diseases left behind.

RESULTS

About a quarter of the respondents (25.5%) had at least one migrant child. Most of the respondents (86.6%) rated their health as poor, and 42.0% of them suffered from physical limitations. Nearly half of the respondents (45.0%) had depressive symptoms, but the vast majority (88.2%) were generally satisfied with their lives. Only a quarter of the respondents received outpatient treatment in the past month while only one fifth of them received inpatient visits in the past year. After controlling for other demographic and socioeconomic variables, it was found in this study that those who with migrant child were more likely to report poor self-rated health (OR = 1.26; 95% CI 1.01-1.58), not satisfied with general life (OR = 1.28; 95% CI 1.03-1.59) and seek outpatient visits (OR = 1.22; 95% CI 1.03-1.43) than those who without migrant child.

CONCLUSION

Our study found that there is a negative association between migration of adult child and physical health, mental health and health care utilization of older parents with chronic diseases left behind, which means a comprehensive effect on their health status. Further health policies should focus on improving the well-being of older parents with chronic diseases left behind.

Income-Related Inequalities in Informal Care: Evidence From the Longitudinal Healthy Longevity Survey in China

Objectives

This report aims to examine income-related inequalities in informal care among older people with functional limitations in China.

Methods

Data are drawn from the 2005, 2008, 2011, and 2014 waves of the Chinese Longitudinal Healthy Longevity Survey. Erreygers concentration index, concentration index, and horizontal inequity index are used to examine inequalities in informal care. A random effects model is then used to investigate the relationship between household income and informal care.

Results

There is no significant association between household income and the probability of receiving informal care. However, we observed a significant positive association between household income and hours of informal care received, indicating that those with higher household income receive more hours of informal care compared to those with lower household income. The degree of this inequality increases as the number of functional limitations increases.

Discussion

Lower household income is associated with lower intensity of informal care received, particularly for older people with more functional limitations. Policies are required to support low-income older people with more functional limitations.

Whose migration matters? The role of migration in social networks and mental health among rural older adults in China

The dual demographic changes in massive rural-to-urban labour migration and population ageing have significantly impacted the lives of older adults, who have either been left behind in rural regions or migrated to urban areas. While many extant studies on migration and wellbeing of older adults have focused on either migrating or left-behind older adults, a very limited number of studies have directly compared these two groups. Utilising data from the China Longitudinal Ageing Social Survey, this study examines the impacts of different migration patterns (i.e. migrating older adults, left-behind older adults and non-migrating older adults) on the social networks and mental health of older adults in rural China. Structural equation modelling results showed that older adults who have been left behind reported weaker family ties and poorer mental health than the other older adults. Moreover, weakened family ties increased older adults’ risk of developing mental health problems. Older migrants reported the lowest level of depressive symptoms among the three groups of older adults. However, migration may be associated with poorer mental health among the older migrants due to the shrinking/weakening of family/friendship ties.

More invisible and vulnerable: the impact of COVID-19 on older persons in displacement in Durumi IDP camp Abuja, Nigeria

Purpose

The novel coronavirus disease (COVID-19) pandemic has further intensified the vulnerability of older persons in displacement and rendered them more unseen. This study aims at exploring the impact of COVID-19 on older people in displacement.

Design/methodology/approach

Data were obtained using semi-structured interviews from 12 older persons at Durumi IDP camp Abuja, while observing strict infection control measures. The data were inductively coded with Nvivo and analysed thematically.

Findings

Findings revealed that the economic and psychosocial fallout of the COVID-19 pandemic has increased older persons in displacement poverty, psychological stress and placed them at risk of ageism, social isolation and may subsequently lead to secondary displacement, thereby losing all progress, development and resilience built after initial displacement.

Social implications

This paper concluded by encouraging the need for all stakeholders to pay more attention to this invisible yet vulnerable group to ensure no one is left behind as people fight through this pandemic and its social implications.

Originality/value

To the best of the authors’ knowledge, this study is the first to explore the impact of COVID-19 on older people in displacement in Nigeria. This is because they have been relatively invisible to research endeavours.

Applying SF-6D to measure health state utilities among the middle and old aged patients with hypertension in China

Purpose

Hypertension is a growing public health problem in China; however, little is known about health-related quality of life (HRQoL) especially health state utility (HSU) of patients with hypertension in rural China. This study aimed to examine the HSU as measured by SF-6D and to investigate its associated factors among middle and old aged patients with hypertension in rural China.

Methods

Data were collected from twelve villages in Shandong Province in 2016. SF-36 was administrated to measure HRQoL of middle and old aged patients with hypertension and was got to the SF-6D values using Hong Kong’s tariff. Descriptive analyses, such as demographic characteristics, socio-economic status, and utility, were stratified by hypertension classification. Multiple linear regression models were applied to assess the associated factors of HSU.

Results

A total of 933 (response rate:86.4%) middle and old aged patients (69.1 ± 8.2 years) with hypertension participated in the study. 39.4% of participants were male; 44.2% had stage I hypertension; 26.4% had stage II and above. The mean score of SF-6D utility score was 0.743 (SD: 0.14, range: 0.32–1.00, median: 0.756, Interquartile range:0.634–0.859). Being female (β = −0.046), having two or more comorbidities (2 vs. 1 β = −0.066; > 3 vs. 1 β = −0.098) and the health expenditure higher than 2000 RMB (2000–3999 vs.< 2000 β = −0.042; 4000–5999 vs. < 2000 β = −0.046; > 6000 vs. < 2000 β = −0.071) were significantly associated with lower SF-6D overall score; while being farmer (β = 0.032), having high household income (10,000–14,999 vs. < 5000 β = 0.045; > 15,000 vs. < 5000 β = 0.064) and having stage I and above hypertension (stage I vs. Normotensive β = 0.047; stage II vs. Normotensive β = 0.079; stage III vs. Normotensive β = 0.095) were significantly associated with higher SF-6D overall score.

Conclusion

SF-6D was capable to measure quality of life middle and old aged patients with hypertension in China. And multiple factors were demonstrated to be significantly associated with quality of life.

How parental migration affects early social-emotional development of left-behind children in rural China: a structural equation modeling analysis

OBJECTIVES

This study assessed the early social-emotional development of left-behind children (LBC) in rural China and determined the mediating factors linking parental migration to LBC's developmental outcome.

METHODS

We used cross-sectional data of 845 LBC under 3 years old from five counties in rural China in 2018. Social-emotional problems were assessed by the ages and stages questionnaires: social-emotional. Family structure, function, and child nurturing care practices were measured to explore their roles in potential pathways of parental migration affecting early social-emotional development.

RESULTS

36.4% of LBC were identified with social-emotional problems; the rate was higher among LBC with migrant parents than those with migrant fathers (39.9% vs. 30.5%, adjusted OR: 1.40 [95% CI 1.01, 1.93]). Results of structural equation modeling reveal that caregivers' low education and depressive symptoms, poor migrant-caregiver communication, family poverty, and no assistant caregiving weakened home parenting environment, and then contributed to LBC's social-emotional problems.

CONCLUSIONS

LBC in early childhood may be at a high risk of social-emotional problems, which are primarily caused by the transition of family structure and function and consequently weakened home environment.

US Migration Status of Adult Children and Cognitive Decline Among Older Parents Who Remain in Mexico

Low- and middle-income countries (LMICs) are experiencing rapid aging, a growing dementia burden, and relatively high rates of out-migration among working-age adults. Family member migration status may be a unique societal determinant of cognitive aging in LMIC settings. We aimed to evaluate the association between adult child US migration status and change in cognitive performance scores using data from the Mexican Health and Aging Study, a population-based, national-level cohort study of Mexico adults aged ≥50 years at baseline (2001), with 2-, 12-, and 14-year follow-up waves (2003, 2012, and 2015). Cognitive performance assessments were completed by 5,972 and 4,939 respondents at 11 years and 14 years of follow-up, respectively. For women, having an adult child in the United States was associated with steeper decline in verbal memory scores (e.g., for 9-year change in immediate verbal recall z score, marginal risk difference (RD) = -0.09 (95% confidence interval (CI): -0.16, -0.03); for delayed verbal recall z score, RD = -0.10 (95% CI: -0.17, -0.03)) and overall cognitive performance (for overall cognitive performance z score, RD = -0.04, 95% CI: -0.07, -0.00). There were mostly null associations for men. To our knowledge, this is the first study to have evaluated the association between family member migration status and cognitive decline; future work should be extended to other LMICs facing population aging.

What Happens to the Health of Elderly Parents When Adult Child Migration Splits Households? Evidence from Rural China

There is little understanding about the effects of adult child migration on the health of elderly parents left behind in the light of economic contribution and time allocation (farm work and emotional cohesion). Using the pooled data from three latest issues of China Health and Retirement Longitudinal Study (CHARLS) in the rural areas, this study assesses the impact of child migration on parents' health by employing instrumental variable approach to deal with the endogeneity problem. Overall, the evidence suggests that adult child migration impairs parental health as indicated by lower self-reported health (SRH), body mass index (BMI), physical activity of daily living (PADL), and higher depression score. Moreover, parents who are female, poorly-educated, and living with one adult child at least are the most vulnerable groups in terms of poor health outcomes. The negative impact of farming burden on the health of parents left behind outweighs the positive impact of economic support and emotional cohesion. Thus, child migration exerts a significantly negative impact on parental health. Establishing medical and social security systems for the elderly is important to complement the traditional family support in rural China.

The association between parental migration and early childhood nutrition of left-behind children in rural China

BACKGROUND

More than one-third of children under 3 years old are left behind at home due to parental migration in rural China, and we know very little about early childhood nutrition of left-behind children (LBC) because of the dearth of research. This study examined the association between parental migration and early childhood nutrition of LBC in rural China.

METHODS

We used repeated cross-sectional data of rural children aged 6-35 months who participated in two surveys in six counties of northern and southern China in 2013 and 2016 respectively. The length, weight, and hemoglobin concentration were measured by trained health-care workers blinded to parental migration status. Stunting, underweight, wasting, and anemia were identified with the standards recommended by WHO. Generalized linear regressions and multivariate logistic regressions were employed to explore the association between parental migration and these nutritional outcomes at each time point.

RESULTS

Two thousand three hundred thirty-six and 2210 children aged 6-35 months were enrolled in 2013 and 2016, respectively. The results show a reduction of the risks of stunting, underweight, and wasting from 2013 (16.4, 8.5, and 3.5%, respectively) to 2016 (12.1, 4.0, and 1.5%, respectively) but highlight a constantly and alarmingly high risk of anemia among these children (44.8% in 2013 and 43.8% in 2016). Children with migrant fathers performed as well as or better than those with non-migrants on these indicators. Children with migrant parents performed slightly worse in 2013, but equal or slightly superior in 2016 on these indicators compared with children with non-migrants and migrant fathers. Children aged 6-17 months with migrant parents had a significantly lower risk of anemia than those living with their mothers or with both parents (43.1% vs. 63.6% and 61.5 in 2013, and 42.5 vs. 60.1 and 66.2% in 2016), even after controlling for children's sociodemographic characteristics.

CONCLUSIONS

Parental migration may be not detrimental and even beneficial to early childhood nutrition of LBC in rural China. Continued nutritional support is needed for all rural children, especially interventions for preventing micronutrient deficiency. Programs for LBC are recommended to continue to focus on nutrition but pay more attention to other important health issues.

The Impact of Rural Labor Migration on Elderly Health from the Perspective of Gender Structure: A Case Study in Western China

Aging and rural labor migration have become two major demographic features in China. Using data of 400 rural households in Sichuan, China in 2015, this study constructs an ordered probit model containing instrumental variables to analyze the effect of rural labor migration on the health of the elderly in the family, from the perspective of the gender structure of migrant labor. The results indicate that the overall impact of labor migration on the elderly’s health is positive, and labor migration in the family has different effects on the health of the elderly by gender. Specifically, the results indicate the following: (1) the joint migration of both male and female labor or the migration of only male labor in a household can have a positive impact; (2) if only female labor migrates, the impact is negative; and (3) although the effect is negative, the migration of only female labor has a more prominent impact on the elderly’s self-rated health, whereas the migration of only male labor has a more significant effect on the elderly’s activities of daily living. Our findings suggest that the differential influence of labor migration by gender on rural elderly health should be considered to ensure the welfare of the elderly.

Socioeconomic disparities in psychological health: Testing the Reserve Capacity Model in a population-based sample of Chinese migrants

Based on the Reserve Capacity Model, this study investigated the associations of objective socioeconomic status and subjective social status with psychological health and the underlying psychosocial mechanisms in a population-based sample of Chinese migrants (n = 15,999). Results showed that subjective social status was positively associated with life satisfaction and self-rated health through the mediation of psychological distress and perceived stress. Whereas education showed a very weak association with life satisfaction, income was directly associated with life satisfaction only. The findings suggest that reducing psychosocial vulnerabilities may be a potential impetus to eliminate socioeconomic health disparities among Chinese migrants.

Having an Adult Child in the United States, Physical Functioning, and Unmet Needs for Care Among Older Mexican Adults

BACKGROUND

Migration of adult children may impact the health of aging parents who remain in low- and middle-income countries. Prior studies have uncovered mixed associations between adult child migration status and physical functioning of older parents; none to our knowledge has examined the impact on unmet caregiving needs.

METHODS

Data come from a population-based study of Mexican adults ≥50 years. We used longitudinal targeted maximum likelihood estimation to estimate associations between having an adult child US migrant and lower-body functional limitations, and both needs and unmet needs for assistance with basic or instrumental activities of daily living (ADLs/IADLs) for 11,806 respondents surveyed over an 11-year period.

RESULTS

For women, having an adult child US migrant at baseline and 2-year follow-up was associated with fewer lower-body functional limitations [marginal risk difference (RD) = -0.14, 95% confidence interval (CI) = -0.26, -0.01] and ADLs/IADLs (RD = -0.08, 95% CI = -0.16, -0.001) at 2-year follow-up. Having an adult child US migrant at all waves was associated with a higher prevalence of functional limitations at 11-year follow-up (RD = 0.04, 95% CI = 0.01, 0.06). Having an adult child US migrant was associated with a higher prevalence of unmet needs for assistance at 2 (RD = 0.13, 95% CI = 0.04, 0.21) and 11-year follow-up for women (RD = 0.07, 95% CI = -0.02, 0.15) and 11-year follow-up for men (RD = 0.08, 95% CI = 0.00, 0.16).

CONCLUSION

Having an adult child US migrant had mixed associations with physical functioning, but substantial adverse associations with unmet caregiving needs for a cohort of older adults in Mexico.

Evolving parent-adult child relations: location of multiple children and psychological well-being of older adults in China

OBJECTIVE

This study examines the interplay among intergenerational emotional closeness, location of multiple children, and parental depressive symptoms in the context of massive migration in rural China.

STUDY DESIGN

This study is based on a longitudinal survey.

METHODS

Longitudinal data were collected from a stratified random sample of age 60 years and older living in rural townships within Chaohu, a primarily agricultural municipal district with massive out-migration in China. In 2009, 1224 individuals completed the survey, and 977 (79.8% of the original participants) were followed up in 2012. We estimate fixed-effects models to examine how changing collective emotional cohesion and the total composition of children's location affect parents' depressive symptoms.

RESULTS

Descriptive analyses show that both the composition of children's location and intergenerational emotional closeness are subject to changes during a 3-year survey interval. Results from fixed-effect models further demonstrate that collective emotional closeness and psychological well-being are positively associated with each other. This association is the strongest when all children are local, but it becomes less prominent when there are more migrant than local children.

CONCLUSIONS

This study has provided important evidence that both intergenerational cohesion and location of multiple children evolve over time and jointly influence parents' psychological well-being in later life. The left-behind older adults are not necessarily the most vulnerable group in rural China. Those with most adult children living close by could also suffer from a deficit in psychological well-being if the emotional bond between them is weak.
