Green space access and mental wellbeing during pregnancy

Pregnancy is a period of major physical, emotional and social change. Regular access to parks, gardens, tree-lined streets and other natural settings may support mental wellbeing, yet the benefits are shaped by safety, transport, housing, climate and the quality of the space. A longitudinal study can show whether patterns of green space exposure are associated with changes in stress, anxiety, mood and social connection across pregnancy and after birth.

For Australian health researchers and services, this topic sits at the intersection of public health, maternity care, urban planning and community wellbeing. In Brisbane and surrounding Queensland communities, a shaded park may be an easy walk for one family and an inaccessible destination for another. Understanding that difference is essential when translating evidence into practical antenatal support.

Why pregnancy is a valuable period to study

Mental health during pregnancy can influence sleep, daily functioning, relationships and preparation for parenthood. Symptoms of depression and anxiety may emerge gradually, fluctuate between trimesters or continue into the postnatal period. Tracking participants over time is therefore more informative than relying on a single survey at one antenatal appointment.

A longitudinal design could recruit people early in pregnancy and collect information during each trimester, shortly after birth and again during the first year of parenting. Researchers might combine validated wellbeing measures with travel diaries, wearable activity data, geographic information system mapping and interviews about how participants experience local places.

This approach can distinguish access from actual use. A park may be close to a home but difficult to reach with limited mobility, poor footpaths, heavy traffic or a lack of shade. In Brisbane’s subtropical climate, heat, humidity and summer storms can affect whether outdoor activity feels restorative or burdensome.

How green space may support maternal wellbeing

Natural environments may offer several overlapping benefits. Gentle walking can support sleep and physical health, while vegetation, birdsong and reduced traffic noise may help the nervous system recover from daily stress. A familiar local park can also provide a predictable setting for social contact, including informal conversations with neighbours or other expectant parents.

The social dimension matters in Australia, where antenatal education, parent groups and community health programs often connect families through local services. Green space can make these relationships easier to sustain when it includes seating, toilets, drinking water, pram-friendly paths and areas suitable for different abilities. Community gardens and shaded playgrounds may serve several generations at once.

Evidence from outside the health sector can also broaden thinking about place-based support. For example, library wellbeing resources illustrate how trusted community settings can connect people with information, social participation and local support. The principle is transferable: wellbeing interventions are more likely to be used when they are embedded in familiar, accessible community networks.

Measuring access beyond distance

Distance to the nearest park is a useful starting point, but it is an incomplete measure of opportunity. Researchers should assess the size, condition and facilities of green spaces, along with whether they are open at suitable times. A small landscaped courtyard may be more useful than a large reserve if it is visible, safe and only a few minutes from home.

Personal circumstances should be recorded alongside environmental exposure. Household income, rental security, car access, work schedules, cultural preferences, disability, visa status and existing mental health conditions can all influence how participants use outdoor areas. First Nations perspectives and connection to Country should be included through respectful partnership and appropriate governance rather than treated as an optional demographic variable.

Queensland data collection also needs to account for seasonal realities. Heatwaves, flooding, bushfire smoke and intense rainfall can temporarily change access to parks. In regional and outer-metropolitan areas, limited public transport may make a nearby reserve effectively inaccessible. In inner Brisbane, dense housing and busy roads can create a different set of barriers.

Designing a study that reflects everyday life

Participant-centred research should allow people to describe what makes a place feel supportive. Short mobile surveys after a walk, photo diaries and interviews can capture experiences that satellite imagery cannot. Questions might cover comfort, safety, privacy, cultural suitability, connection with others and whether the visit improved mood.

Researchers can compare several exposure patterns: consistent access, declining access, increasing access and little or no access. This makes it possible to examine whether changes in green space use precede changes in wellbeing, while recognising that people experiencing poorer mental health may also reduce activity or avoid public places.

Useful study features include:

• Repeated wellbeing assessments across pregnancy and after birth
• Objective and participant-reported measures of green space exposure
• Inclusion of urban, suburban, regional and remote communities
• Analysis of heat, flooding, transport and safety conditions

Practical variables worth recording include:

• Shade, seating, toilets, water and pram-friendly paths
• Distance to parks by walking, public transport and car
• Social connection, perceived safety and cultural comfort
• Changes in housing, employment, health or caring responsibilities

Implications for Australian health services

Antenatal services could use findings from this research to provide more tailored advice about safe, realistic outdoor activity. A midwife, general practitioner or allied health professional might identify a nearby shaded route, community garden or indoor-outdoor gathering rather than giving generic advice to “exercise more”. Referrals should account for pregnancy complications, mobility limitations and the person’s own preferences.

The research also has value for councils and planners. Investment in tree canopy, accessible paths, lighting, water points and public toilets can support families well beyond pregnancy. Brisbane’s parks, creek corridors and neighbourhood greenways offer opportunities, while Queensland’s heat requires design that makes outdoor use comfortable during much of the year. Local consultation can help identify which improvements residents will actually use.

Health translation partnerships can connect these findings with broader prevention work. Research on community-based approaches to childhood health, including a childhood obesity program evaluation, shows why sustained local engagement and evaluation matter. Supporting wellbeing during pregnancy may also create healthier routines and stronger social networks that continue into the early years of a child’s life.

Moving from evidence to action

The influence of green space access on mental wellbeing during pregnancy is unlikely to be explained by one factor alone. Place, relationships, physical activity, safety and environmental comfort interact with individual circumstances. A strong longitudinal study should therefore avoid treating greenery as a simple prescription and instead examine the conditions that make nature accessible, welcoming and useful.

For Brisbane Diamantina Health Partners and its research, health service and community partners, this is an opportunity to connect environmental data with lived experience. Collaborative projects can include maternity services, universities, councils, consumer representatives, community-controlled organisations and urban designers. Findings should be returned to participating communities in clear formats and translated into service pathways and planning decisions.

Researchers and partners can connect through Brisbane Diamantina to support evidence that moves from observation to implementation. Prioritise inclusive measurement, fund long-term follow-up and design green spaces around the realities of pregnancy, parenting and Queensland life.
