RESUMO

Although prominent models of alcohol use and abuse implicate stress as an important motivator of alcohol consumption, research has not consistently identified a relationship between stress and drinking outcomes. Presumably stress leads to heavier alcohol consumption and related problems primarily for individuals who lack other adaptive methods for coping effectively with stressful experiences. To test this hypothesis, we examined four adaptive coping approaches (active coping, planning, suppression of competing activities, and restraint), as predictors of alcohol use and related problems as well as moderators of relations between stress and drinking outcomes in an undergraduate population (N=225). Further, we examined coping motives for drinking as potential mediators of the effects of coping strategies as well as stress by coping strategy interactions. Analyses supported both restraint and suppression of competing activities as moderators of the influence of stress on alcohol use but not problems. The stress by restraint interaction was also evident in the prediction of coping motives, and coping motives were related to higher levels of both weekly drinking and alcohol-related problems. Finally, coping motives for drinking served to mediate the stress by restraint interaction on weekly drinking. Overall, these results suggest that efforts to suppress competing activities and restrain impulsive responses in the face of stress may reduce the risk for heavy drinking during the transition from high school to college.

RESUMO

PURPOSE: To establish normative data for children on the Words-in-Noise Test (WIN; R. H. Wilson, 2003; R. H. Wilson & R. McArdle, 2007). METHOD: Forty-two children in each of 7 age groups, ranging in age from 6 to 12 years (n=294), and 24 young adults (age range: 18-27 years) with normal hearing for pure tones participated. All listeners were screened at 15 dB HL (American National Standards Institute, 2004) with the octave interval between 500 and 4000 Hz. Randomizations of WIN Lists 1, 2, and 1 or WIN Lists 2, 1, and 2 were presented with the noise fixed at 70 dB SPL, followed by presentation at 90 dB SPL of the 70 Northwestern University Auditory Test No. 6 (T. W. Tillman & R. Carhart, 1966) words used in the WIN. Finally, the Peabody Picture Vocabulary Test-Revised (L. M. Dunn & L. M. Dunn, 1981) was administered. Testing was conducted in a quiet room. RESULTS: There were 3 main findings: (a) The biggest change in recognition performance occurred between the ages of 6 and 7 years; (b) from 9 to 12 years, recognition performance was stable; and (c) performance by young adults (18-27 years) was slightly better (1-2 dB) than performance by the older children. CONCLUSION: The WIN can be used with children as young as 6 years of age; however, age-specific ranges of normal recognition performance must be used.

RESUMO

BACKGROUND: Men are believed to have more visceral adipose tissue (VAT) than women have, but studies in African Americans that measured VAT from a single computed tomography (CT) slice found no sex difference. OBJECTIVE: We used a serial-slice CT scan to investigate whether there is a sex difference in VAT volume among African Americans. DESIGN: Single-slice CT measurements of VAT area at lumbar spine L2-3 and L4-5 levels were taken in 110 African Americans (44 men, 66 women). In 59 subjects (24 men, 35 women), VAT volume was also measured with contiguous CT slices from the diaphragm to the iliac crest. Fat mass was determined by dual-energy X-ray absorptiometry. RESULTS: Men and women had similar ages (x +/- SD: 36.1 +/- 7.8 and 35.6 +/- 7.8 y, respectively) and body mass indexes in kg/m(2) (29.5 +/- 6.9 and 32.0 +/- 8.9). The percentage of body fat was lower (P < 0.0001) in men (21.8 +/- 7.3%) than in women (37.4 +/- 7.9%). The VAT volume was greater (P = 0.01) in men (1443 +/- 931 cm(3)) than in women (940 +/- 821 cm(3)). There was no sex difference in unadjusted VAT area at L2-3 (men, 88.6 +/- 63.5 cm(2); women, 57.2 +/- 45.4 cm(2)) or L4-5 (men, 65.6 +/- 53.3 cm(2); women, 55.0 +/- 38.3 cm(2)). After adjustment for percentage of body fat or fat mass, men had larger VAT area at both levels (P < 0.01). After adjustment for body mass index, the sex difference in VAT area was detectable at L2-3 (P < 0.001) but not at L4-5 (P = 0.22). CONCLUSIONS: VAT volume is greater in men than in women. Detection of sex differences in VAT area among African Americans on single-slice CT requires adjustment for body fat content. At L2-3, adjustment for body mass index alone is adequate to detect sex differences in VAT.
