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.

Strollo, MD 3 1 Psychology, University <strong>of</strong> Pittsburgh, Pittsburgh, PA; 2 Psychiatry, University <strong>of</strong> Pittsburgh, Pittsburgh, PA and 3 Pulmonary, Allergy, and Critical Care <strong>Medicine</strong>, University <strong>of</strong> Pittsburgh, Pittsburgh, PA. Sleep is associated with physical and psychological health and quality <strong>of</strong> life. Few studies have measured multiple aspects <strong>of</strong> sleep simultaneously in one investigation. The current study examined the influence <strong>of</strong> ethnicity, gender, and socioeconomic status (SES) on both objective and subjective dimensions <strong>of</strong> sleep in 46 African Americans and 55 Caucasians (49.5% male), ages 35 to 78. Two nights <strong>of</strong> in-home polysomnography (PSG), and ten nights <strong>of</strong> 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 <strong>of</strong> 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 <strong>of</strong> 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 <strong>of</strong> 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. CORRESPONDING AUTHOR: Elizabeth J.

Lugo, BA Psychology, 1 Karla Espinosa de los Monteros, BA. 2 and Linda C. Gallo, PhD 2 1 Psychology, San Diego State University, San Diego, CA and 2 Clinical Psychology, SDSU/UCSD JDP, San Diego, CA. 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 <strong>of</strong> 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 <strong>of</strong> SSS) and physiological risk factors relevant to CVD. Objective measures <strong>of</strong> SES and SSS as predictors <strong>of</strong> CVD risk factors in ethnic minority populations were examined. Perceived SSS, in the U.S., was examined as a predictor <strong>of</strong> 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 <strong>of</strong> increased blood pressure. Although research has suggested that SSS might be a better predictor <strong>of</strong> 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 <strong>of</strong> risk <strong>of</strong> CVD, was found to be in the opposite direction than expected. While some may believe that SSS is a better predictor <strong>of</strong> health outcomes than objective measures <strong>of</strong> SES, further research is needed to look into the utility <strong>of</strong> the SSS measure in low-SES minority populations.

Lugo, BA, 2 Gregory A. Talavera, MD 2 and Linda C. Gallo, PhD 1 , 2 1 Clinical Psychology, SDSU/UCSD JDP in Clinical Psychology, San Diego, CA and 2 San Diego State Univeristy, San Diego, CA. 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 <strong>of</strong> socioeconomic position (ABSMs) and health. We examined whether a neighborhood index <strong>of</strong> economic deprivation (index

Participants were 145 middle aged (M = 47.03 years) Latinas with low SES recruited from health clinics along the Mexico-California border. Women completed assessments <strong>of</strong> U.S acculturation (ARMSA-II) and physiological risk factors. Hierarchal regression analyses indicated that higher U.S acculturation and lower neighborhood deprivation predicted lower serum glucose (p
