OBJECTIVE: The primary purpose of the present study was to examine the relationship between daily stressors and physical symptoms in college-age women with a childhood history of sexual abuse and women without a history of childhood sexual abuse. It was hypothesized that women with a history of childhood sexual abuse would be particularly susceptible to the effects of daily stressors on physical symptoms, and would show more covariation between daily stressors and physical symptoms, compared to women without a history of childhood sexual abuse. METHOD: Female college students (n = 491) were screened for histories of childhood (before age 15) and adulthood (after age 15) contact sexual abuse. Of these participants, 18 women with only a history of childhood sexual abuse were assigned to the SA group, and 27 women with no history of childhood or adulthood sexual abuse were assigned to the NA group. These women filled out self-report measures of daily hassles and physical symptoms for 28 consecutive days. RESULTS: During the 5 days preceding a highly stressful day, women in the SA group reported significantly more physical symptoms than during the 5 days preceding a day of low stress. For the NA group, there were no significant differences in reported physical symptoms between high- and low-stress days. CONCLUSIONS: The pattern of results for physical symptoms suggests that women with a history of childhood sexual abuse may be particularly susceptible to the effects of heightened daily stress, and may display this susceptibility in the report of physical symptoms. Possible explanations for these findings are discussed. 相似文献

OBJECTIVE: Previous research has indicated that women who experience childhood physical abuse or childhood sexual abuse are at increased risk for posttraumatic stress disorder (PTSD) and adult victimization. Recently, peritraumatic dissociation (PD) has been suggested as another possible risk factor for PTSD and adult victimization. The purpose of the present study was to investigate the effects of childhood physical and sexual abuse and PD on PTSD and adult victimization. METHOD: A sample of 467 female college students completed questionnaires about childhood and adult sexual and physical abuse experiences, PD, and PTSD symptoms. RESULTS: The combined sexual and physical abuse (CA) and sexual abuse only (SA) groups reported significantly higher numbers of PTSD symptoms than the physical abuse only (PA) and no abuse (NA) groups. The CA and PA groups reported significantly more adult sexual and physical victimization than the SA and NA groups. Across all four groups, higher levels of PD were associated with higher levels of PTSD and adult sexual and physical victimization. CONCLUSIONS: The results of the current study suggest that different types of childhood abuse may lead to different adult problems. The results also indicated that PD may have a broad effect on PTSD development and adult victimization. 相似文献

Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min?1 with the intensity individualized at ～ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions. 相似文献

OBJECTIVE: The purpose of this study was to examine the relationship between a history of physical and/or sexual abuse and current suicidality in college-age women. It was hypothesized that abuse history would significantly predict level of suicidality. A secondary hypothesis was that abuse status would predict attitudes about life and death. METHOD: Female college students (n = 707) were screened for histories of childhood (before age 15) and adulthood (after age 15) contact sexual abuse and physical abuse sequelae. Ninety-five women reported a history of childhood sexual abuse, 116 adult sexual abuse, 104 child physical abuse, and 55 adult physical abuse. Participants completed measures of attitudes about life and death and current suicidal ideation. RESULTS: Child physical abuse and child sexual abuse accounted for variance in current suicidal ideation. Adult sexual abuse explained variance in positive attitudes about life. Adult physical abuse, adult sexual abuse, and child sexual abuse accounted for variance in negative attitudes about life. Finally, child sexual abuse and adult sexual abuse accounted for variance in fear of death. CONCLUSIONS: Detailed assessment of female college students' abuse histories should facilitate understanding of their level of suicide risk. Patterns of attitudes about life and death may also be informative. 相似文献

The aim of this study was to compare the somatotype and size of elite female basketball players in terms of playing position and team performance. Anthropometry and somatotype data were collected on 168 players from 14 countries before the Women's World Basketball Championship, Australia, 1994. There were 64 guards (mean?±?s: age 25.4?±?3.3 years, height 1.72?±?0.06?m, mass 66.1?±?6.2?kg, somatotype?=?2.9?–?3.9?–?2.6), 57 forwards (age 25.2?±?3.8 years, height 1.81?±?0.06?m, mass 73.3?±?5.9?kg, somatotype?=?2.8?–?3.5?–?3.2) and 47 centres (age 24.1?±?3.1 years, height 1.90?±?0.06?m, mass 82.6?±?8.2?kg, somatotype?=?3.2?–?3.1?–?3.4). Mean somatotypes by position were significantly different (F?=?7.73, P?<?0.01). Guards had greater mesomorphy than centres and less ectomorphy than forwards and centres. When discriminant function analysis was applied to endomorphy, mesomorphy, ectomorphy, age, height and mass, only height, mass and ectomorphy entered (Wilks' λ?=?0.351, F?=?31.40, P?<?0.000), 70% of the variance was accounted for, and 72% of players were correctly classified. In the four top versus four bottom teams, guards were taller and more ectomorphic, forwards were taller, with lower mesomorphy and higher ectomorphy, and centres did not differ. Thus there are some differences in somatotypes by position and team placing, but the combination of height, mass and ectomorphy provide the best differentiation by position. 相似文献

Physical child abusers and adults at risk for child abuse, relative to comparison subjects, are reported to be more physiologically reactive to child-related stressors. It is not known if the reported physiological reactivity is child specific or if physical child abusers and at-risk parents are also more reactive to other types of stressful stimuli. The present study investigated changes in heart rate and skin conductance in response to four types of non-child-related stressors in at-risk and matched low-risk mothers. The four types of stressful stimuli were: a cold pressor; a stressful film depicting industrial accidents; unsolvable anagrams; and an aversive car horn. At-risk mothers, relative to low-risk mothers, had greater and more prolonged sympathetic activation during presentations of the cold pressor and the stressful film, the stimuli rated as the most stressful. The present data, combined with previous findings, support the view that generalized sympathetic activation to both child and non-child-related stressors may serve as a mediator of physical child abuse. 相似文献

OBJECTIVE: The present study describes factors related to fatal abuse in three age groups in the United States Air Force (USAF). METHOD: Records from 32 substantiated cases of fatal child abuse in the USAF were independently reviewed for 60 predefined factors. RESULTS: Males were over-represented in young child victims (between 1 year and 4 years of age) and child victims (between 4 years and 15 years of age) but not in infant victims (between 24 hours and 1 year of age). African-American infant victims and perpetrators were over-represented. Younger victims were more likely to have been previously physically abused by the perpetrator. Perpetrators were predominantly male and the biological fathers of the victims. Infant and young child perpetrators reported childhood abuse histories, while child perpetrators reported the highest frequency of mental health contact. Victims' families reported significant life stressors. Families of young child victims were more likely divorced, separated, or single. Incidents with infants and young children tended to occur without witnesses; incidents with child victims tended to have the victim's sibling(s) and/or mother present. Fatal incidents were more frequent on the weekend, in the home, and initiated by some family disturbance. CONCLUSIONS: Differences among groups in factors related to infant and child homicide across age groups may assist in the development of more tailored abuse prevention efforts and may also guide future investigations. 相似文献
