or compared to the normal-weight women during both conditions. There were no
significant group*condition interactions or main effects for total activity or sedentary,
moderate, or vigorous activity time (P>0.05).
CONCLusION: Acute sleep deprivation and obesity may influence dietary intake at
certain times of the day but does not appear to acutely influence physical activity or
physical activity intensity. Additional work examining the relationship between sleep
deprivation and energy balance pathways is needed.

OBJECTIVE: The purpose of this study was to examine the relationship between
sleep (duration and quality) and diet quality among young adult women. Subjects:
Three-hundred seventy-five women (18-24 years) were recruited to participate in the
study. Measurements: Each participant wore an actigraph for 7 consecutive nights to
measure sleep. Sleep logs were used to verify bedtime and wake time for each night.
Actigraph data was then evaluated to determine sleep latency, efficiency, and number
of awakenings. Diet was evaluated using automated self-administered 24-hour recall
over three nonconsecutive days. Diet quality was evaluated using the 2005 Healthy
Eating Index (HEI 2005), consumption of fruits and vegetables and consumption of
non-nutrient dense foods (NNDF).
rEsuLTs: On average women in the study consumed 1980 ± 540 calories per day,
1.2 ± 0.7 servings of fruits and vegetables per 1000 calories and 27.4 ± 11.9% of their
calories from junk foods. The average Healthy Eating Index score was 59.3 ± 12.5,
which is classified as “needs improvement.” The HEI 2005 was negatively related to
bedtime (F = 7.89, p = 0.0053) and the coefficient of variation in wake time (F = 5.13,
p = 0.0242). Fruit and vegetable consumption was negatively related to wake time (F
= 9.85, p = 0.0019)and the coefficient of variation in wake time (F = 6.34, p = 0.0123).
NNDF was positively related to bedtime (F = 4.82, p = 0.0289).
CONCLusIONs: Result for this study suggest that young adult women who go to
sleep earlier, wake up earlier and have more consistent sleep patterns eat less NNDF,
more fruits and vegetables and better meet dietary recommendations than women who
go to sleep later, wake up later and have less consistent sleep patterns.

OBJECTIVE: To analyze the adiposity changes over 30 year-period, according to the
nutritional status in students.
METhOds: Sample is part of the Ilhabela Mixed-Longitudinal Project on Growth
and Physical Fitness*, which is held since 1978. From a data base of 16.000 students of
both sexes, 1144 students, 635 males and 509 females, from 10 to 11 years-old met the
following inclusion criteria: to be in the prepubertal stage of sexual maturation; to be
apparently healthy; and do not have physical impairments.The selected data were part
of a database from 1978/1980 (Initial), 1988/1990 (10 years), 1998/2000 (20 years) and
2008/2010 (30 years). The variables analyzed were: body mass, body height and fatness:
average of seven skinfolds. Children were categorized according to the nutritional status
through the WHO body mass index curves for age and sex in normal, overweight and
obese. Used was ANOVA one-way, followed by post-hoc Scheffé was p
