Childhood morbidity and adulthood ill health
Insights
Childhood health predicts adult well-being, but most adult ill health originates from healthy childhoods. Early health status has long-term implications for adult health outcomes.
Area of Science:
- Developmental psychology
- Public health
- Epidemiology
Background:
- Childhood health status is a potential predictor of adult health.
- Understanding long-term health trajectories is crucial for public health interventions.
- The National Child Development Study provides a valuable cohort for examining developmental health patterns.
Purpose of the Study:
- To investigate the relationship between childhood health and ill health in early adulthood.
- To determine if childhood morbidity predicts adult health outcomes.
- To assess the long-term implications of early health status on adult well-being.
Main Methods:
- Utilized data from the National Child Development Study, linking health at age 7 to health at age 23.
- Developed a comprehensive measure of health status using a wide range of childhood health information.
- Analyzed morbidity groups and chronic conditions in childhood against adult health indices.
Main Results:
- Children with no reported childhood morbidity maintained a health advantage into adulthood across multiple indices.
- Higher childhood morbidity, including chronic conditions and asthma, was associated with increased adult ill health.
- Despite long-term implications, the majority of adult ill health occurred in individuals with a relatively healthy childhood.
Conclusions:
- Childhood health status has demonstrable long-term implications for adult health.
- Early health does not substantially contribute to the overall burden of ill health in early adult life.
- Further research is needed to understand the multifactorial nature of adult ill health.
Study Objective:
The aim of the study was to investigate the relationship between the state of health in childhood and ill health in early adult life.
Design:
The study used data collected as part of the National Child Development Study and related health at 7 years of age to that at 23. A wide range of information on child health in the cohort was available, which was used to construct a broader measure of health status than selected diagnostic categories.
Setting:
The survey population was nationwide.
Participants:
The study population included all children born in the week 3-9 March 1958. They were followed up at 7, 11, 16, and 23 years. Of the target population of 17,733 births, 12,537 (76%) were retraced and interviewed at 23.
Measurements And Main Results:
Children at age 7 were allocated to 13 morbidity groups; 20% of children had reported no ill-health apart from the common infectious diseases, but 10% were included in four or more of the morbidity groups. Children with no reported morbidity retained their health advantage into early adulthood: ratios of observed to expected ill health for four of the five indices examined at age 23 were all significantly below one (self rated health 0.81, asthma and/or wheezy bronchitis 0.63, allergies 0.79, emotional health 0.75). Children with more morbidity at age 7 had higher ratios of ill health in adulthood. A chronic condition in childhood was associated not only with excess morbidity in the short term but also with a poor health rating in early adult life (ratio = 1.38). Morbidity was significantly increased for most of the adulthood indices among children with asthma and/or wheezy bronchitis. However most ill health in young adulthood occurred in study members with a relatively healthy childhood.
Conclusions:
Although the state of health in childhood has long term implications, it does not form a substantial contribution to ill health in early adult life.
