Social integration and pulmonary function in the elderly.

ABSTRACT: This study sought to determine whether social integration, defined as number of social roles, is associated with better pulmonary function in the elderly and which roles are associated with greatest benefit. It also examined pathways that connect social integration to better lung health.High functioning men (n = 518) and women (n = 629) ages 70-79 were recruited as part of the MacArthur Study of Successful Aging, and data were collected on social roles as well as pulmonary function as assessed by peak expiratory flow rate (PEFR). Multiple regressions predicting PEFR from the number of social roles controlled for age, sex, race, education, weight, and height. Physiological, behavioral, social, and psychological factors were tested as mediators of the association between the number of social roles and PEFR.More social roles were associated with better PEFR. Analysis of specific roles indicated that marriage was the strongest positive correlate of PEFR. However, greater numbers of roles were also associated with better PEFR independent of marriage. Being a relative or friend were each also individually associated with better PEFR. Even so, greater numbers of social roles were associated with better PEFR independent of relative and friend. The data were consistent with greater happiness, not smoking, and more physical activity acting as pathways linking the number of roles to PEFR.Number of social roles is an important correlate of healthy lung function in the elderly. This association may be driven by healthier behaviors and greater feelings of well-being.

Project description:BackgroundPulmonary tuberculosis (TB) can impair pulmonary function (PF), especially in the elderly. The risk factors associated with the severity of PF impairment in the elderly with pulmonary TB remain unclear. Hence, this retrospective study aimed to address this issue to help improve the management of TB in the elderly population.MethodsFrom January 2019 to February 2022, the elderly who were admitted to our hospital for pulmonary TB and underwent PF testing were included in this analysis. The forced expiratory volume in one second percent of predicted (FEV1% predicted) and clinical characteristics were collected and analyzed retrospectively. The extent of impaired PF was then categorized based on the FEV1% predicted and classified as grade 1-5. Logistic regression analysis was used to analyze the risk factors for impaired PF.ResultsA total of 249 patients who met the enrollment criteria were included in this analysis. According to the results of FEV1% predicted, all patients were classified as grade 1 (n = 37), grade 2 (n = 46), grade 3 (n = 55), grade 4 (n = 56), or grade 5 (n = 55). Statistical analysis showed that albumin (adjusted odds ratio (aOR) = 0.928, P = 0.013), body mass index (BMI) < 18.5 kg/m2 (aOR = 4.968, P = 0.046), lesion number ≥ 3 (aOR = 4.229, P < 0.001), male (aOR = 2.252, P = 0.009), respiratory disease (aOR = 1.669, P = 0.046), and cardiovascular disease (aOR = 2.489, P = 0.027) were related to the impairment of PF.ConclusionsPF impairment is common in the elderly with pulmonary TB. The male sex, BMI < 18.5 kg/m2, lesion number ≥ 3, hypoproteinemia, and respiratory and cardiovascular comorbidities were identified as risk factors for significant PF impairment. Our findings highlight the risk factors associated with PF impairment, which may be helpful to improve the current management of pulmonary TB in the elderly to save their lung function.

Project description:BackgroundImpaired pulmonary function (IPF) and left ventricular systolic dysfunction (LVSD) are prevalent in the elderly and are associated with significant morbidity and mortality. The main objectives of this study were to examine the relative impact and joint association of IPF and LVSD with heart failure, cardiovascular mortality and all-cause mortality, and their impact on risk classification using a continuous net reclassification index.Methods and resultsWe followed 2342 adults without prevalent cardiovascular disease (mean age, 76 years) from the Cardiovascular Health Study for a median of 12.6 years. LVSD was defined as LV ejection fraction <55%. IPF was defined as: forced expiratory volume in 1 second:forced vital capacity <70%, and predicted forced expiratory volume in 1 second <80%. Outcomes included heart failure hospitalization, cardiovascular mortality, all-cause mortality, and composite outcome. LVSD was detected in 128 subjects (6%), IPF in 441 (19%) and both in 38 (2%). Compared to those without LVSD or IPF, there was a significantly increased cardiovascular risk for groups of LVSD only, IPF only, and LVSD plus IPF, adjusted hazard ratio (95% CI) 2.1 (1.5-3.0), 1.7 (1.4-2.1), and 3.2 (2.0-5.1) for HF; 1.8 (1.2-2.6), 1.4 (1.1-1.8), and 2.8 (1.7-4.7) for cardiovascular mortality; 1.3 (1.0-1.8), 1.7 (1.4-1.9), and 2.1 (1.5-3.0) for all-cause mortality, and 1.6 (1.3-2.1), 1.7 (1.5-1.9), and 2.4 (1.7-3.3) for composite outcome, respectively. Risk classification improved significantly for all outcomes when IPF was added to the adjusted model with LVSD or LVSD to IPF.ConclusionsWhile risk of cardiovascular outcomes was the highest among elderly with both LVSD and IPF, risk was comparable between subjects with IPF alone and those with LVSD alone. This observation, combined with improved risk classification by adding IPF to LVSD or LVSD to IPF, underscore the importance of comprehensive heart and lung evaluation in cardiovascular outcome assessment.
