Malnutrition among a hunter-gatherer group

A San group in Namibia faces malnutrition due to a dysfunctional local food system, with no agency over food sources and limited access to traditional foods. The researchers recommend context-specific solutions, including eliminating movement restrictions and supporting traditional foodways to supplement diets with key nutritional groups.

Urbanization and agriculture are land uses that most affect Brazil's rivers

A nationwide survey of land use impacts on water quality in Brazil reveals that agriculture and urbanization are the main culprits behind river pollution. The study found that degradation varies according to scale or dimension used to evaluate it, and that catchment analysis appears to best reflect overall water quality.

Adolescent girls at risk for self-injury can be identified using a short psychological profile

A study identified three key factors that predict the first occurrence of nonsuicidal self-harm in adolescent girls: low conscientiousness, high avoidance, and parental substance abuse history. These psychological vulnerabilities were found to distinguish girls who initiated self-harm from those who did not.

Failure to calibrate for ethnicity in fracture epidemiology would do more harm than good

The Fracture Risk Assessment Tool (FRAX) is widely used to predict major osteoporotic fractures, but experts warn that failing to calibrate for ethnicity could lead to large errors in fracture risk assessment. Ethnicity-specific models have been calibrated for specific populations, and their inclusion is crucial for accurate stratifica...
