boys, WC was a significant predictor of VO2max controlling for
BMI (R2 = .38); whereas for girls, BMI, was a significant predictor
of VO2max (R2 = .31) controlling for WC.
These results suggest that excess body mass and abdominal fat
influence physical fitness. Additionally, gender and ethnicity
determine whether total body mass or abdominal adiposity
affects fitness. Weight loss programs involving a physical activity
component should consider ethnicity, gender, BMI, and WC when
establishing fitness goals.

Sleep is associated with physical and psychological health and
quality of life. Few studies have measured multiple aspects of sleep
simultaneously in one investigation. The current study examined
the influence of ethnicity, gender, and socioeconomic status (SES)
on both objective and subjective dimensions of sleep in 46 African
Americans and 55 Caucasians (49.5% male), ages 35 to 78.
Two nights of in-home polysomnography (PSG), and ten nights
of actigraphy and self-report sleep data were collected. African
Americans had shorter sleep duration (ps < .05) and poorer sleep
efficiency (ps < .05) as measured by PSG and actigraphy, and spent
less time in Stage 3-4 sleep (p < .01) compared to Caucasians.
Furthermore, African Americans reported poorer quality of sleep
on the Pittsburgh Sleep Quality Index (PSQI; p < .01) than did
Caucasians. Although men had shorter sleep duration (ps < .01)
and poorer sleep efficiency (ps < .05) as measured by PSG and
actigraphy, and spent less time in Stage 3-4 sleep (p < .05) than
did women, men reported better quality of sleep on the PSQI
and in sleep diaries (ps < .05). Relatively few associations between
SES and sleep parameters were observed in African Americans
and Caucasians, taken separately. Exploratory analyses revealed
that neither race nor gender differences in sleep were accounted
for by differences in depression and perceived stress. In sum, race
and gender influence dimensions of sleep and these effects are not
accounted for by the measured psychological or socioeconomic
factors. Race and gender differences in sleep characteristics may play
a role in race and gender differences in health.

SES has commonly been measured using relatively objective indices
based on education, income, and occupation, and has been shown
to strongly influence health status. Research has shown that the
association between health and a person’s perceived social status
may be a better predictor of health risks than traditional objective
social position. In the current study, 142 Mexican-American
women (mean age = 47.12 years) completed assessment for SSS
(MacArthur Scale of SSS) and physiological risk factors relevant
to CVD. Objective measures of SES and SSS as predictors of
CVD risk factors in ethnic minority populations were examined.
Perceived SSS, in the U.S., was examined as a predictor of CVD
risk factors beyond objective SES. Physiological risk factors included
systolic blood pressure (SBP), diastolic blood pressure (DBP), waist
circumference, serum cholesterol, and serum glucose. SSS in the
U.S. was significantly related to social support (p < .001), inversely
related to anxiety (p = .024), and marginally, inversely related to
depression. Perceived social status was also significantly related to
SBP (p < .001), DBP (p = .013), serum glucose (p < .001), and
marginally related to serum cholesterol. Perceived social status was
significantly related to psychosocial risk factors in the direction
expected, although, higher perceived social status was found to
be predictive of increased blood pressure. Although research has
suggested that SSS might be a better predictor of health outcomes,
this may not be the case for low SES Latinas. Consistent with
previous research, the current study found that SSS was significantly
related to psychosocial risk factors and most physiological risk
factors, however, blood pressure, a key component of risk of
CVD, was found to be in the opposite direction than expected.
While some may believe that SSS is a better predictor of health
outcomes than objective measures of SES, further research is needed
to look into the utility of the SSS measure in low-SES minority
populations.

Increased acculturation to the U.S mainstream culture is
associated with significant changes in CVD risk among Latinos.
Studies also suggest a relationship between area-based measures
of socioeconomic position (ABSMs) and health. We examined
whether a neighborhood index of economic deprivation (index
