Maintaining & Building Activity-Friendly Places in Aruba

SLOTH Model of Physical Activity

• Sleep

• Leisure

• Occupation

• Transportation

• Household

What is being done to improve PA?

• Minor investment in programs• Guided by theories that emphasize

psychological & social influences• Primary goals are education and

behavior change skills training targeting individuals

• Fragmented, poorly coordinated, poorly funded approaches

Psychosocial Models of Health Behavior

IndividualBiologicalPsychologicalSkills

Social/Cultural

Will individual interventions ever be sufficient?

Interventions based on psychosocial theories can be effective

But not sufficientReach is limitedEffects are modestMaintenance is rare

Programs are not designed to change the root causes of current behavioral patterns

Places for Physical Activity• Leisure

• Occupation

• Transportation

• Household

• Parks, health clubs, sidewalks

• Workplace

• Streets, bike facilities

Multiple Pathways from Land Use to Health: Walkability Associations With Active Transportation,

Body Mass Index, and Air Quality.Frank et al. JAPA 2007

• 5% increase in walkability associated with:– 32% increase in walking for transport– ¼ point decrease in BMI (about 1.25 pounds)– 6.5% decrease in vehicle miles traveled– 5.6% decrease in oxides of nitrogen (NOx)

grams– 5.5% decrease in volatile organic compounds

(VOC) grams• County government is acting on results

Accelerometer-based MVPA Min/day in Walkability-by-Income Quadrants

Walkability: F=13.74; p =.000Income: F=2.59; p =.108Walkability X Income: F=.001; p =.981

* Adjusted for gender and age

Walkable neighborhoods encourage more walking in older adults

•Older women who live within walking distance of trails, parks or stores recorded significantly higher pedometer readings than women who did not. The more destinations that were close by, the more they walked.

Main Results• Walking for transport (30 min/day for at least 5 days/week) was positively associated with:

– Street density (POR 1.71, 95% CI 1.19-2.46)– Street connectivity (POR 2.21, 95% CI 1.40-3.49)– Bus Rapid Transit stations in the neighborhood (POR

1.71, 95% CI 1.19-3.47)

• Leisure time physical activity (30 min/day for at least 5 days/week) was positively associated with:

– Park density (POR 2.05, 95%CI 1.13-3.72)– Bus Rapid Transit stations in the neighbohood (POR

1.27, 95% CI 1.07-1.50)

People with access to parks & recreationFacilities are more likely to be active

A national study of US adolescents (N=20,745)* found a greater number of physical activity facilities is directly related to physical activity and inversely related to risk of overweight

Neighborhood Walkability and Active Commuting to School

• 201 parents of children aged 4 to 17• Active commuting to school:

– 25% in hi-walkable neighborhoods– 11% in lo-walkable neighborhoods

• Parent concerns, mostly about traffic, were higher in lo-walkable neighborhoods
