GENETICS OR KINETICS? Data from the Finnish Twin Cohort
were used to examine whether familial factors might help explain
mortality differences by physical activity levels that have been
observed in studies of unrelated individuals. Increased levels of
physical activity were associated with decreased mortality for the
entire cohort. For same-sex pairs of twins who were healthy at baseline,
but discordant for death during follow-up, the risk of death declined
for those with higher levels of physical activity. See "Relationship
of Leisure-Time Physical Activity and Mortality: The Finnish Twin
Cohort," by Kujala, Kaprio, Sarna, and Koskenvuo in JAMA 279: 440-444
WALKING MAY REDUCE RISK OF DIABETES: Dr. Elizabeth Mayer-Davis,
of the University of South Carolina, School of Public Health, and
colleagues from the Insulin Resistance Atherosclerosis Study examined
whether physical activity is associated with better insulin sensitivity,
which has been shown to be linked to a reduced risk of diabetes.
They found that an increase in non-vigorous as well as vigorous
physical activity was associated with significantly higher insulin
sensitivity. The authors suggest that regular moderate physical
activity on most days of the week may decrease the risk of diabetes.
See "Intensity and Amount of Physical Activity in Relation to Insulin
Sensitivity: The Insulin Resistance Atherosclerosis Study," by Mayer-Davis,
D’Agostino, Karter, Haffner, Rewers, Saad, and Bergman in JAMA 279:
PHYSICAL ACTIVITY AND STROKE: Data from the Northern Manhattan
Stroke Study were used to investigate the reationship between physical
activity and stroke in an urban, elderly, multi-ethnic population.
The authors found that leisure time physical activity was related
to a decreased occurrence of ischemic stroke and suggest that more
emphasis on physical activity is needed in stroke prevention campaigns.
See " Leisure-time Physical Activity and Ischemic Stroke Risk: The
Northern Manhattan Stroke Study, " by Sacco, Gan, Boden-Albala,
Lin, kargman, Hauser, Shea, and Paik in Stroke 29: 380-387 (1998).
ADOLESCENTS ATTEMPT TO LOSE WEIGHT: Data from students participating
in the Massachusetts Youth Risk Behavior Survey were analyzed to
determine eating patterns and dietary factors associated with adolescents’
attempts to lose weight. Unhealthy eating and exercise were commonly
observed, highlighting the need for effective nutrition and weight
counseling among adolescents. See " Eating Patterns, Physical Activity,
and Attempts to Change Weight Among Adolescents," by Middleman,
Vasquex and Durant in the Journal of Adolescent health 22: 37-42
