Physical activity during early life and the risk of all-cause mortality in midlife: findings from a birth cohort study.

ABSTRACT:

Background

The objective of this study was to examine the association between physical activity during childhood and adolescence and the risk of all-cause mortality in midlife. We analyzed data from a birth cohort (The 1958 National Child Development Survey), including births in England, Wales and Scotland.

Methods

Physical activity was assessed using questionnaires at ages 7, 11 and 16. Death certificates defined all-cause mortality. Cumulative exposure, sensitive and critical periods, and physical activity trajectory from childhood to adolescence were tested using multivariate Cox proportional hazard models. The sweep the death was confirmed was defined as the time event.

Results

From age 23 to 55, 8.9% of participants (n = 9398) died. Physical activity in childhood and adolescence affected the risk of all-cause mortality in midlife. In men, physical activity at ages 11 [hazard ratio (HR): 0.77; 95% confidence interval (CI): 0.60-0.98] and 16 (HR: 0.60; 95% CI: 0.46-0.78) was associated with reduced risk of all-cause mortality. In women, physical activity at age 16 (HR: 0.68; 95% CI: 0.48-0.95) was associated with reduced risk of all-cause mortality. Physical activity in adolescence eliminated the risk of all-cause mortality associated with physical inactivity in adulthood in women.

Conclusions

Physical activity during childhood and adolescence was associated with reduced risk of all-cause mortality with different effects by sex.

Project description:ObjectivesEarly-life adversities (ELAs) such as child maltreatment (neglect and abuse) and socioeconomic disadvantage have been associated with adult mortality. However, evidence is sparse for specific types of ELA. We aimed to establish whether specific ELAs (ie, different types of child maltreatment and socioeconomic disadvantage) were associated independently with all-cause mortality in mid-adulthood and to examine potential intermediary pathways.DesignProspective cohort study.Setting1958 British birth cohort: a longitudinal, population-based sample of individuals born in Great Britain during a single week in March 1958.Participants9310 males and females with data on child maltreatment and mortality (44/45-58 years).Outcome measuresMortality follow-up from 2002/2003 to 2016 when participants were aged 44/45-58 years. Death was ascertained via the NHS Central Register (N=296) or cohort maintenance activities (N=16).ResultsPrevalence of ELAs ranged from 1.6% (sexual abuse) to 11% (psychological abuse). Several, but not all, ELAs were associated with increased risk of premature death, independent of covariates and other adversities; adjusted HRs were 2.64 (95% CI 1.52 to 4.59) for sexual abuse, 1.93 (95% CI 1.45 to 2.58) for socioeconomic disadvantage, 1.73 (95% CI 1.11 to 2.71) for physical abuse and 1.43 (95% CI 1.03 to 1.98) for neglect. After adjustment for covariates and other adversities, no associations with mortality were observed for psychological and witnessing abuse. Regarding potential intermediaries (including adult socioeconomic factors, behaviours, adiposity, mental health and cardiometabolic markers), most associations attenuated after accounting for adult health behaviours (particularly smoking). In addition, early-life socioeconomic disadvantage and neglect associations attenuated after accounting for adult socioeconomic factors. The association for sexual abuse and premature mortality was largely unaffected by potential intermediaries.ConclusionsAssociations with premature mortality varied by type of ELA: associations for sexual and physical abuse, neglect and socioeconomic disadvantage were independent of each other. Different types of ELAs could influence premature mortality via different pathways; this requires further research.

Project description:ImportanceEarly-life mental health is known to be associated with socioeconomic adversity and psychological distress in adulthood, but less is known about potential associations with biomarkers and mortality.ObjectiveTo investigate the association between early-life mental health trajectories with biomarkers in midlife and premature mortality.Design, setting, and participantsThis study used data from the British National Child Development Study, a population-based birth cohort. The initial sample of 17 415 individuals consisted of all infants born in Great Britain in a single week in 1958. Analysis began Feburary 2017 and ended May 2020.Main outcomes and measuresBiomarkers collected at age 44 to 45 years were fibrinogen, C-reactive protein, glycated hemoglobin, high- and low-density lipoprotein cholesterol, forced expiratory volume, blood pressure, and waist-to-hip ratio. Information on all-cause mortality was available up to age 58 years and cause-specific mortality up to age 50 years.ResultsBiomarkers were analyzed from 9377 participants (age, 44-45 years, 4712 female [50.3%]) and mortality data from 15 067 participants (age, 58 years; 7379 female [49.0%]). A 4-group longitudinal typology of early-life conduct problems and affective symptoms was identified: (1) stable low, (2) teacher-identified adolescent onset, (3) moderate, and (4) stable high. Compared with the stable-low group, the stable-high (B, 2.308; 95% CI, 0.213-4.404) and teacher-identified adolescent-onset (B, 2.114; 95% CI, 0.725-3.503) groups had less favorable levels of fibrinogen in middle age. Effect modification was observed by sex (P < .005) such that compared with the stable-low group, differences in high-density lipoprotein and abdominal obesity were only observed in female individuals. The stable-high and teacher-identified adolescent-onset groups had elevated risk for all-cause mortality (hazard ratio, 1.878; 95% CI, 1.501-2.350 and hazard ratio, 1.412; 95% CI, 1.174-1.698). Psychopathology-associated mortality was higher in both groups but unintentional injuries-associated mortality only in the stable-high group.Conclusions and relevanceExperiencing affective symptoms and conduct problems in childhood and adolescence is associated with less favorable levels of biomarkers 28 years later and elevated risk of premature mortality. These findings, if causal and generalizable to younger cohorts, may imply that effective interventions on early-life mental health have the potential to shift the distribution of risk and improve population health.

Project description:BACKGROUND: Physical inactivity is a major public health problem associated with increased mortality risk. It is, however, poorly understood whether vigorous physical activity is more beneficial for reducing mortality risk than activities of lower intensity. The aim of this study was to examine associations of the intensity and volume of leisure-time physical activity with all-cause mortality among middle-aged women and men while considering sociodemographic and health related factors as covariates. METHODS: Questionnaire survey data collected in 2000-02 among 40-60-year-old employees of the City of Helsinki (N = 8960) were linked with register data on mortality (74% gave permission to the linkage) providing a mean follow-up time of 12-years. The analysis included 6429 respondents (79% women). The participants were classified into three groups according to intensity of physical activity: low moderate, high moderate and vigorous. The volume of physical activity was classified into three groups according to tertiles. Cox regression analysis was used to calculate hazard ratios (HR) and 95% confidence intervals (CIs) for all-cause mortality. RESULTS: During the follow up 205 participants died. Leisure-time physical activity was associated with reduced risk of mortality. After adjusting for covariates the vigorous group (HR = 0.54, 95% CI 0.34-0.86) showed a reduced risk of mortality compared with the low moderate group whereas for the high moderate group the reductions in mortality risk (HR = 0.72, 95% CI 0.48-1.08) were less clear. Adjusting for the volume of physical activity did not affect the point estimates. Higher volume of leisure-time physical activity was also associated with reduced mortality risk; however, adjusting for the covariates and the intensity of physical activity explained the differences. CONCLUSIONS: For healthy middle-aged women and men who engage in some physical activity vigorous exercise may provide further health benefits preventing premature deaths.
