Abstract

Background: The Global Burden of Disease (GBoD) report suggests that high BMI, smoking, hypertension and physical inactivity are the major risk factors (in that order) for chronic disease in Australasia. This is based on population attributable risks (PAR), which explain how much the burden from a specific disease would be reduced, if the effects of a single causal risk factor were eliminated. Estimates of PAR depend on the strength of the association between risk factors and disease, and the prevalence of the risk factor in the population. The aim of this study was to estimate changes in PARs for ischaemic heart disease attributable to these four major risk factors, across the adult lifespan in women.
Methods: Younger (age 18-23 years at baseline; N=14175), mid-age (45-50; N=13205), and older (70-75; N=11574) women, recruited by random sampling from the Medicare data base, completed 3-yearly mailed surveys for the Australian Longitudinal Study of Women’s Health (ALSWH) from 1996 to 2012. Prevalence estimates (P) for high BMI, smoking, high blood pressure and inactivity were obtained from the ALSWH for women in 15 age groups, using category cutpoints described in the GBoD report. Age and gender specific relative risks (RR) were extracted from the GBoD database. Population attributable risks (PAR) for each risk factor over 12 years were calculated using the formula: PAR=P(RR-1)/1+P(RR-1).
Results: The PAR for smoking decreased from a high of 59% at age 22-27 to a low of 5.3% at age 70-75. The PAR for physical inactivity was higher than for high BMI across the lifespan, ranging from 51% in the young cohort at age 31-36, to around 25% in the older cohort, compared with a range of 33% at age 31-36 years, to 11% at age 85-90, for BMI. PARs for high blood pressure were lowest across the lifespan, ranging from 3% in the young cohort to 10% in the older cohort.
Discussion: In women, the population attributable risk of inactivity (for IHD) is higher than for any of the other major risk factors from age 30 to 90 years. This is in contrast with the GBoD report which suggests that high BMI is the major cause of ill health in Australasian adults. The data support the case for greater investment in physical activity promotion across the adult lifespan.
