Rural Upbringing Linked to Childhood Mental Health Outcomes in Australia

Between roughly one quarter and one third of all Australians live outside the nation’s major cities, and for decades health researchers, policymakers and families alike have assumed that growing up far from a metropolitan centre must carry a mental health penalty for children. A new longitudinal study, one of the few of its kind to follow rural and city children from before birth into the preschool years, suggests the picture is far more reassuring than that assumption implies, while also uncovering a sharp warning for one particularly vulnerable group.

The research, published in Child Psychiatry & Human Development, drew on data from 595 women and their children enrolled in the Mercy Pregnancy and Emotional Wellbeing Study, a prospective pregnancy cohort recruited from Melbourne and Perth as well as from rural and remote regions of Western Australia including the mid-west, south-west and goldfields. All mothers joined the study before the twentieth week of pregnancy and were assessed repeatedly through the third trimester, birth, six months, twelve months and finally when their children reached three to four years of age. Of the children, 432 lived in major metropolitan areas and 163 lived in regional, rural or remote communities, a split that allowed the research team to compare the two settings directly across the earliest years of life.

Classifying where families lived was itself a technical exercise. The researchers used the Modified Monash Model, an Australian system that grades locations from MM1, the major cities, through to MM7, the most remote communities, based on both geographic remoteness and road distance from population centres with health services. Because the rural sample was too small to analyse each of the six rural categories separately, MM2 through MM7 were combined into a single rural group. The choice of this classification matters: unlike simple population counts used in the United States, the Modified Monash Model is built around relative access to healthcare resources, which is precisely the mechanism most often blamed for rural health disadvantage.

Child mental health at three to four years was measured with unusual rigour for this age group. Trained researchers administered the Preschool Age Psychiatric Assessment, a structured diagnostic interview completed with mothers that generates DSM-5 diagnoses through a computer algorithm, capturing emotional disorders such as depression and anxiety as well as behavioural disorders including oppositional defiant disorder, conduct disorder and attention deficit hyperactivity disorder. In parallel, mothers completed the Child Behavior Checklist for ages 1.5 to 5, a well-validated dimensional measure of internalising symptoms, such as withdrawal and anxiety, and externalising symptoms, such as aggression and hyperactivity. Maternal depression was tracked with the Edinburgh Postnatal Depression Scale across pregnancy and the postpartum, stressful life events were counted at each wave, and parenting stress was measured with the Parenting Stress Index at six months, twelve months and four years.

The central finding was striking for its simplicity: when the researchers compared diagnostic rates and symptom levels between rural and metropolitan children, adjusting for maternal age, education, ethnicity, parity and relationship status, they found no significant differences. The prevalence of emotional and behavioural disorders, and of elevated internalising or externalising symptoms on the checklist, was statistically indistinguishable between the two groups, and the effect sizes of the differences were small. Rural women actually reported somewhat lower depressive symptoms across the follow-up period than their city counterparts, and the trajectories of stressful life events over time followed similar U-shaped patterns in both groups, declining during pregnancy before rising through the postpartum years.

The study did, however, expose a substantial gap in one domain: early education and care. Rural children were roughly twice as likely to receive no childcare at six months of age, with an adjusted odds ratio of 2.43, and again at twelve months, with an odds ratio of 2.14, after demographic factors were controlled. By three to four years of age the pattern persisted in reverse: only 14.1 percent of rural children were attending kindergarten compared with 29.2 percent of metropolitan children, an adjusted odds ratio of 0.50. Whether this reflects parental preference or simple lack of availability is unclear from the data, but the finding chimes with qualitative research describing rural Australia as peppered with so-called childcare deserts, areas where organised early childhood services are so scarce that families who want them cannot obtain them.

The most consequential result emerged when the researchers tested whether maternal depression and its treatment interacted with where a family lived. For diagnosed maternal depressive disorder combined with no antidepressant use, a statistically significant interaction with rurality appeared for the dimensional symptom measures. Children of rural mothers with untreated depression scored, on average, 10.07 points higher on the internalising scale and 9.78 points higher on the externalising scale of the Child Behavior Checklist than the children of metropolitan mothers in the same clinical situation, differences that were both statistically significant. No such interaction appeared for the diagnostic interview outcomes, and children of mothers whose depression was treated with antidepressants did not show the same rural penalty, a pattern that underscores how much may hinge on whether perinatal depression is actually treated.

The workforce context behind that finding is sobering. Australian data cited in the study indicate that metropolitan areas average 13.3 full-time-equivalent psychiatrists per 100,000 population, compared with only 2.5 to 6 in regional and rural areas, while psychologist availability falls from 77.5 full-time equivalents in cities to between 18.8 and 48.9 elsewhere. Child and perinatal mental health specialists are likely scarcer still. Prior research has shown that barriers to mental health care in rural communities exceed those for physical health care, and that delays between symptom onset and seeking professional treatment are significantly longer for rural adults, a gap that is almost certainly wider for preschool children whose conditions depend entirely on adult recognition and referral.

At the same time, the study identified features of rural family life that may be protective. Rural children spent more time with their mothers across infancy and had less screen time, and while most measures of home activities such as reading and singing showed no group differences, these factors, alongside lower reported maternal depressive symptoms, suggest that rural upbringing is not uniformly adverse. The results align with a large United States study reporting stronger social support for children and emotional support for caregivers in rural areas, and with a recent Australian meta-analysis of adolescents that found poorer depression and anxiety prevalence in metropolitan rather than rural young people.

The authors are careful about limitations. The six rural remoteness categories had to be pooled, masking heterogeneity among the mid-west, south-west and goldfields communities where recruitment occurred. The study did not measure fathers’ or partners’ mental health, and the numbers were insufficient to examine the mental health of Aboriginal and Torres Strait Islander children. And the children were followed only to three or four years of age, before the age window, spanning middle childhood and adolescence, in which most mental disorders first emerge and in which differences masked in early childhood could yet appear.

Even so, the findings carry a clear message for clinicians and policymakers. For the general population of rural families, the presumed burden of country upbringing on preschool mental health was not borne out, and some elements of the rural environment looked favourable. But maternal depression left untreated in a rural setting appears to amplify risk for the child in ways it does not in the city, plausibly because specialist services, childcare and kindergarten, all of which can buffer the effects of parental illness, are harder to reach. With more than a quarter of Australian births occurring outside major cities, the researchers argue that identifying vulnerable children early, and ensuring that mothers with perinatal depression in rural communities actually receive treatment, may be among the most effective levers available for protecting the next generation’s mental health.
