Changes in cardiovascular disease risk and behavioural risk factors before the introduction of a health check programme in England

Abstract

A population-based programme of health checks was introduced for adults in England in 2011 for the primary prevention of cardiovascular diseases (CVD) and risk factors management. The aim was to evaluate changes in cardiovascular risk and behavioural risk factors in a health check eligible population in England from 1994 to 2013, by using repeated cross-sectional design using seven surveys of the Health Survey for England. Measures included traditional CVD risk factors and behavioural risk factors. Linear trends were estimated allowing for sampling design. The surveys comprised 49,805 adults aged 45 to 74years; 30,639 were free from cardiovascular comorbidity; 16,041 (52%) had complete data for quantitative risk factors. Between 1994 and 2013, systolic blood pressure decreased by 3.1 (95% confidence interval 2.5 to 3.6) mmHg per decade in men and 5.0 (4.5 to 5.5) in women. Total cholesterol decreased by 0.20 (0.16 to 0.24) mmol/l per decade in men; 0.23 (0.19 to 0.26) in women. Smoking declined by 6% (5% to 8%) per decade in men; 7% (6% - 8%) in women. The proportion with CVD-risk ≥20% declined by 6.8% per decade in men; 2.4% in women. Multiple behavioural risk factors were strongly associated with estimated CVD-risk, but improving trends in traditional CVD risk factors were inconsistent with increasing indicators of adiposity. Long-term declines in traditional risk factors contributed to reductions in estimated CVD-risk prior to the introduction of a health check programme. Behaviour change interventions for multiple risk factor exposures remain a key area for future research.

Evolution of the “fourth stage” of epidemiologic transition in people aged 80 years and over: population-based cohort study using electronic health records

“…Our findings reveal that increases in diabetes risk extend to all age-groups of senior elderly beyond 80 years of age. Increasing risk of cancer in all age-groups of our cohort is supported by reports from Cancer Research UK for individuals aged 75 and over [41], as well as increasing adiposity indicators and obesity [30] reported for the UK in recent decades.…”

Developing the role of electronic health records in economic evaluation

“…Primary care EHRs include data concerning the results of clinical and laboratory tests and records of lifestyle behaviors. Analysis of these data can provide aggregate results that are consistent with estimates from national survey data for variables including smoking [24] and blood pressure [25,26]. Test results are not regularly recorded over time as might be expected in a clinical trial; instead there is risk of confounding by indication because physicians order tests when there is a reason to do so.…”

The Effect of Alcohol on Cardiovascular Risk Factors: Is There New Information?

“…Behavioral risk factors such as overweight and obesity, poor diet, sedentarism or low physical activity, excessive alcohol consumption, and smoking have been correlated with a higher incidence and prevalence of CVD, diabetes, and dementia [8,14,15]. A recent systematic review reported that non-smoker individuals, with a moderate alcohol consumption, who were physically active and followed a healthy diet showed a lower risk of all-cause mortality (66%) than those that had none or only one of these healthy behaviors [15].…”
