Family upheaval causes stress induced physical probelms in adoelscents

A study in the journal Developmental Psychology, says family turmoil and violence causes stress-induced physical problems in adolescents.

The presence of a responsive, supportive mother, however, appears to reduce the negative physiological changes. This study is the first to look at how maternal responsiveness may protect against cumulative risk.

The findings suggest the physiological toll of coping with multiple stress events is significantly greater than with that of coping with a single event.

The researchers used an index called "allostatic load" to measure stress-induced changes in neuroendocrine hormonal systems, cardiovascular responses and metabolism, which indicate the severity of wear and tear on organs and tissues, the university said.
