Long-term health effects of a school construction program

Area of Science:

• Public Health
• Health Economics
• Epidemiology

Background:

• Non-communicable diseases (NCDs) pose a significant burden in low- and middle-income countries (LMICs).
• There is a lack of context-specific evidence on policies affecting NCD risk factors in LMICs.
• Understanding the long-term health impacts of large-scale social programs is crucial for public health policy.

Purpose of the Study:

• To estimate the long-term impact of a large-scale primary school expansion program in Indonesia on NCD risk factors.
• To investigate sex-specific effects of educational expansion on health outcomes.
• To identify potential pathways linking educational interventions to NCD risk.

Main Methods:

• Utilized data from two large-scale Indonesian surveys.
• Employed quasi-experimental methods to assess the impact of the 1970s primary school expansion program.
• Analyzed NCD risk factors including overweight, high waist circumference, high blood pressure, diabetes, and cardiovascular disease diagnoses.

Main Results:

• The school expansion program led to increased likelihood of overweight and high waist circumference among women in non-Java regions.
• These effects in women were partly attributed to increased consumption of high-calorie packaged and take-away foods.
• No significant impacts were found on high blood pressure, diabetes, or cardiovascular disease diagnoses for either sex.
• Women reported improved health outcomes in their early 40s, but these benefits diminished by their mid-40s.

Conclusions:

• Educational expansion programs can have unintended consequences on NCD risk factors, particularly in women, through dietary changes.
• While body weight increased, the program did not significantly elevate the incidence of major NCDs like diabetes or cardiovascular disease.
• The long-term health benefits of such educational interventions on NCDs may be limited or transient, highlighting the need for comprehensive health strategies.
