Socio-demographic and lifestyle factors associated with multimorbidity in New Zealand

Abstract: OBJECTIVES: The incidence of multimorbidity (MM) and its correlates among older adults remain poorly understood. This study aimed to examine the socio-demographic and lifestyle factors associated with MM in New Zealand.METHODS: People aged 55-70 years were invited to participate in a population-based cohort study, the Health Work and Retirement Study, in 2006. Those who accepted the invitation and completed the baseline questionnaire were followed up on a biennial basis. Data on socio-demographic factors, heal… Show more

“…Supporting these ndings, in a Canadian study population, the incidence of multimorbidity was higher in obese participants, but not in those with normal BMI [21]. Obesity and a lack of physical activity have previously been identi ed to be a signi cant predictor of multimorbidity in adults aged > 55 years in New Zealand [22]. Furthermore, in a cohort study from Iran, obese participants had an OR that was 2.33-fold higher than participants with a normal BMI [23].…”

“…Only five of the 14 studies reported an overall IR in addition to group-specific rates. 109 , 121 , 123 , 126 , 132 Across studies reporting incidence, the median (unadjusted) incidence rate was 30.7 per 1,000 person-years (IQR 39.5 per 1,000 person-years) and the median (unadjusted) cumulative incidence was 2.8% (IQR 28.7%). Incidence rates ranged from 1.26 to 342 per 1,000 person-years.…”

“…Most studies did not stratify IRs by sex, with only one reporting IRs among male and female participants separately 130 ; this study reported a higher IR among women than in men. Of the 11 studies reporting race and/or ethnicity, five reported incidence rate(s) stratified by race and/or ethnicity, 109 , 112 , 123 , 129 , 132 one adjusted incidence rates for race and/or ethnicity, 136 and two presented both adjusted overall and stratified incidence rate(s) by race and/or ethnicity. 129 , 130 Two studies consisting solely of South and East Asian ethnicities (Malay, Chinese, and Indian) 110 , 112 reported higher IRs than the remaining studies reporting IRs in White, Non-White, Black/African-American, Hispanic, and Māori populations.…”

“…The multimorbidity measure has further limitations. Although it is a standard approach that has been used in other studies of multimorbidity [45,[80][81][82], this dichotomized variable does not account for the severity, complexity, or duration of the chronic conditions studied. Second, independent variables were limited to the variables available in NHIS.…”
