This paper examines the impact of the out-migration of adult children on older parents' inter-generational support and psychological wellbeing in rural China. The sample comprised 1,237 older Chinese people aged 60 or more years in the rural province of Anhui, China, who completed baseline and follow-up questionnaires in 2001 and 2003, respectively. The differences between older parents with and without migrant children in 2001 in their support and psychological wellbeing in 2003 were examined using independent t-tests, as were changes over the two years in support and wellbeing. Multiple regression models were used to examine the impact of baseline out-migration on the psychological wellbeing of older parents at follow-up. The results showed that, compared to parents without migrant children in 2001, the parents of migrants had significantly more monetary support, less instrumental support, and a lower level of depression in 2003. Such differences may be attributed to different support resources and health status, but the regressions revealed that when the positive effect of inter-generational support was taken into account, older parents with more migrant children tended to have significantly more depression and lower life satisfaction. The findings point to the importance of continued inter-generational support after out-migration in maintaining parental wellbeing.

As the world's most populous country with the largest aging population and a rapidly growing economy, China is receiving increased attention from both the Chinese government and the governments of other countries that face low fertility and aging problems. This unprecedented shift of demographic structure has repercussions for many aspects of development including economic growth, social welfare, elder care, and other public welfare issues in China. Balancing population aging and economic growth requires innovative strategies and represents both challenges and opportunities for China.

Objective: To determine the prophylactic efficacy of short-term intensive preoperative inspiratory muscle training on the incidence of postoperative pulmonary complications in patients scheduled for cardiac surgery. Design: Single-blind, randomized controlled pilot study. Setting: TEDA International Cardiovascular Hospital, China. Subjects: In total, 197 subjects aged ⩾50 years scheduled for cardiac surgery were selected. Intervention: The intervention group (n = 98) received five days of preoperative inspiratory muscle training on top of the usual care received by the patients in the control group (n = 99). Main measures: The primary outcome variable was the occurrence of postoperative pulmonary complications. The secondary outcome variables were inspiratory muscle strength, lung function and length of hospitalization. Results: After cardiac surgery, a total of 10 (10.2%) of the 98 patients in the intervention group and 27 (27.3%) of 99 patients in the control group had postoperative pulmonary complications (risk ratio, 0.23; 95% confidence interval (CI), 0.09-0.58, P = 0.002). The study revealed that, compared with the control 828212C RE0010.1177/0269215519828212Clinical RehabilitationChen et al.
