Key result

Early-life socioeconomic disadvantage linked to ~28% higher odds of midlife obesity and hypertension.

95% CI 1.19-1.38

Why the study?

Early-life exposures can increase the risk of adult obesity and high blood pressure, motivating an exploration of exposures across five childhood domains as predictors of obesity and high blood pressure comorbidity in the 1958 National Child Development Study for comparison with the 1970 British Cohort Study.

Do early-life exposures across five childhood domains predict obesity and high blood pressure comorbidity at age 44 in a British birth cohort?

Key Points

To identify early-life exposures across five childhood domains and evaluate them as predictors of combined obesity and high blood pressure at age 44.
Analyzed data from 9150 participants in the 1958 National Child Development Study (NCDS) followed prospectively from birth to midlife.
Assessed five childhood domains: prenatal/birth, developmental attributes/behavior, education/academic ability, socioeconomic factors, and parental/family environment using stepwise backward elimination.
Predicted midlife comorbidity—defined as BMI ≥ 30 kg/m² and blood pressure > 140/90 mmHg at age 44—using multivariable logistic regression models.
Midlife obesity and high blood pressure comorbidity occurred in 4% (n=395/9150) of participants, with individual prevalences of 24% for obesity and 11% for high blood pressure.
The multivariable model incorporating all childhood domain risk scores, sex, and ethnicity achieved an AUC of 0.70 (95% CI 0.67–0.72), increasing to 0.73 (95% CI 0.71–0.76) after adding adult factors.
Childhood socioeconomic factors were the strongest domain predictor of comorbidity (OR 1.28, 95% CI 1.19–1.38; OR 1.29, 95% CI 1.19–1.39 after adjusting for adult factors), whereas the parental and family environment domain was not significant (OR 1.08, 95% CI 0.94–1.24).

Do early-life exposures across five childhood domains predict obesity and high blood pressure comorbidity at age 44 in a British birth cohort?

P

Population

9,150 British adults (50.2% female) from the 1958 National Child Development Study birth cohort with measured height, weight, and blood pressure at age 44, followed from birth to midlife.

E

Exposure

Exposures across five pre-hypothesized early-life domains (measured at birth or age 11): 1) prenatal, antenatal, neonatal and birth, 2) developmental attributes and behaviour, 3) child education and academic ability, 4) socioeconomic factors, and 5) parental and family environment.

O

Outcome

Combined obesity (BMI ≥ 30 kg/m²) and high blood pressure (average systolic BP ≥ 140 mmHg and/or average diastolic BP ≥ 90 mmHg) comorbidity phenotype measured at age 44 during a biomedical sweep.composite

Main Result

Odds Ratio: 1.28 (95% CI 1.19–1.38)

Early-life exposures—particularly childhood socioeconomic disadvantage, birth health, development, and education—remain robust predictors of midlife obesity and hypertension comorbidity even after accounting for adult lifestyle and socioeconomic factors.

Limitations

No bootstrap resampling, cross-validation, or split-sample internal validation was performed for the predictive models
Long-term cohort attrition and missing data ranging from 5% to 19% across variables
Significant under-representation of individuals from non-White ethnic backgrounds
Reliance on BMI without additional adiposity measures such as waist circumference or body fat percentage
High blood pressure definition relied solely on measured blood pressure at age 44 without accounting for prior hypertension diagnosis or antihypertensive medication use
Lack of direct measures of sedentary behaviour and comprehensive dietary intake in adulthood
Potential model instability, sample dependence, and overfitting from backward stepwise elimination
No bootstrap resampling, cross-validation, or split-sample internal validation was performed, so reported measures represent apparent model performance.
The predictive models demonstrated only modest discrimination (AUC 0.70-0.73), limiting suitability for individual-level risk prediction or public health decision-making.
Missing data ranged from approximately 5% to 19% across variables in the analytical sample, requiring multiple imputation.
Domain-specific risk scores were model-derived predicted values entered as continuous predictors, so their scale does not correspond to a directly interpretable unit of measurement.

Implication

May warrant early socioeconomic screening in cardiometabolic risk models; extends domain-specific predictors from the 1970 to 1958 British birth cohort.

Abstract

BACKGROUND: Early-life exposures can increase the risk of both obesity and high blood pressure in adulthood. In this paper, we identify exposures across five pre-hypothesised childhood domains, explore them as predictors of obesity and high blood pressure comorbidity using the 1958 National Child Development Study (NCDS), and discuss these results in comparison to a similar approach using another birth cohort (1970 British Cohort Study (BCS70)). METHODS: The analytical sample included 9150 participants. The outcome was obesity (BMI of ≥ 30) and high blood pressure (blood pressure > 140/90 mm Hg) comorbidity at age 44. Domains included: 'prenatal, antenatal, neonatal and birth', 'developmental attributes and behaviour', 'education and academic ability', 'socioeconomic factors' and 'parental and family environment'. Stepwise backward elimination selected variables for inclusion for each domain, and predicted risk scores of obesity-high blood pressure for each cohort member within each domain were calculated. We performed multivariable logistic regression analysis including domain-specific risk scores, sex and ethnicity to assess how well the outcome could be predicted taking all domains into account. In additional analysis, we included potential adult factors. RESULTS: Including all domain-specific risk scores, sex and ethnicity in the same prediction model the area under the curve was 0.70 (95% CI 0.67-0.72). The strongest domain predictor was the socioeconomic factors domain (OR 1.28 95% CI 1.19-1.38), similar to the BCS70 results. The parental and family environment domain was not a significant predictor (OR 1.08 95% CI 0.94-1.24) unlike the BCS70 results. After considering adult predictors, robust associations remained to the socioeconomic, education and academic abilities, development and behaviour, and prenatal, antenatal, neonatal and birth domains. CONCLUSIONS: In the NCDS, some early-life course domains were significant predictors of obesity-high blood pressure comorbidity, supporting previous findings. Shared early-life characteristics could have a role in predicting obesity-high blood pressure comorbidity, particularly for those who faced socioeconomic disadvantage.

Stannard et al. (2026) conducted a cohort in Obesity and high blood pressure comorbidity at midlife (n=9,150). Early-life socioeconomic factors domain risk score vs. Lower domain-specific risk score (continuous predictor) was evaluated on Obesity (BMI ≥ 30 kg/m²) and high blood pressure (> 140/90 mm Hg) comorbidity at age 44 (OR 1.28, 95% CI 1.19-1.38). Early-life socioeconomic disadvantage was the strongest domain predictor of obesity and high blood pressure comorbidity at age 44 (OR 1.28, 95% CI 1.19-1.38; model AUC 0.70).
