Abstract
The prevalence of chronic diseases among immigrants varies across different ethnic groups attributed to the disparities in their risk factors. This study aimed to explore the prevalence and correlates of chronic diseases among the rapidly growing South Asian population in Australia.
An online survey was administered (2020–2021) among South Asian immigrants in Australia. Diagnosed chronic diseases, smoking habits, physical activity, alcohol consumption, body mass index, and fruit and vegetable intake were assessed. A multivariable logistic regression model was used to examine factors associated with chronic disease.
Overall, 50% of the study participants had one chronic disease and 39% had more than one chronic disease (n = 282). Back pain (30%), depression (22%), diabetes (21%), hypertension (19%), and heart disease (12%) were the most reported diseases. Approximately 78% of participants were insufficiently active and 38% regularly consumed alcohol. Approximately three-quarters consumed fruits and vegetables less than once per day. Multivariable analyses showed that those who were aged more than 50 years (OR = 4.38, 95% CI 1.66–11.56), consumed alcohol more than once/month (OR = 3.25, 95% CI 1.17–8.96), and ate less than one serving of vegetables/day (OR = 2.94, 95% CI 1.19–7.26) had higher odds of having two or more chronic diseases.
Fifty percent of study participants presented with preventable diseases, signifying a substantial health burden. Public health interventions should primarily focus on reducing alcohol intake and increasing fruit and vegetable consumption, particularly among individuals of advanced age, to reduce the overall burden on the healthcare system.
