Usefulness of the protection motivation theory in explaining hearing protection device use among male industrial workers.

The present study examined the usefulness of personal variables: noise annoyance, and components of the protection motivation theory (R. W. Rogers, 1983) along with social-organizational factors in explaining hearing protection device (HPD) use among Israeli manufacturing workers. Participants were 281 men exposed to harmful noise levels for which routine HPD use is required by regulation. In practice, 3 HPD user groups were identified: nonusers (n?=?38), occasional users (n?=?125), and regular users (n?=?118). HPD use was objectively verified. HPD use was primarily related to the personal variables but not to management pressure, coworker pressure, or family support. The most powerful predictors of HPD use were perceived self-efficacy (for long-term HPD use), perceived susceptibility (to hearing loss), and noise annoyance, together explaining 48% of the outcome variance. These findings have implications for interventions aimed at motivating workers to use HPDs regularly. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hostility and hearing protection behavior: the mediating role of personal beliefs and low frustration tolerance

The authors examined whether hostility would negatively be associated with occupational health behavior, namely, the use of hearing protection devices (HPDs). Also examined as possible mediators were the protection motivation theory (PMT) components and low frustration tolerance (LFT). Participants were 226 male industrial workers, all exposed to potentially hearing-damaging noise. Hostility was negatively related to HPD use. It moderately correlated with the PMT components: negatively with perceived susceptibility, severity, effectiveness, and self-efficacy and positively with perceived barriers. Hostility correlated highly with LFT. Regression analyses confirmed the mediating role of perceived barriers, low self-efficacy, and LFT in the negative relationship between hostility and the use of HPDs. Thus, intrapsychic characteristics of hostile people may be significant for hearing protection behavior.     

Most comfortable loudness shift as a measure of speech attenuation by hearing protectors

The feasibility of using most comfortable loudness (MCL) as a real-world measure of speech attenuation introduced by hearing protection devices (HPDs) was studied. The authors compared three insert HPDs and an earmuff under three test conditions: (a) monaural earphone listening, (b) binaural earphone listening, and (c) sound field listening. The earmuff was used only in the sound-field condition. In addition, three sets of fitting instructions were utilized. Twelve normal hearing subjects participated. Results indicate that MCL shift can be used as a simple measure of speech attenuation provided by HPDs. The observed MCL shifts were affected by the fitting instruction but not by the listening condition. Findings support the notion that MCL-based tests of speech attenuation by HPDs can be conducted reliably both in sound field and under earphones and may be a simple and valid tool for assessing changes in speech audibility due to the wearing of HPDs.     

A hearing conservation program for Wisconsin youth working in agriculture

Adolescents working in agricultural settings may be exposed to noise levels that result in hearing loss. The article describes the design, implementation, and results of a four-year, hearing conservation program (HCP) conducted at school. Thirty-four schools (753 students) were randomly assigned to either an intervention or control group. The intervention included multicomponent educational strategies and employed features of an industrial HCP. Final compliance surveys indicated 87.5% of intervention students reported using hearing protection devices (HPD) at least some of the time, compared to 45% of control students. The HCP components with the greatest reported influence were distribution of HPDs for use on the farm and yearly hearing tests. Eighty percent of intervention students reported intention to use HPDs in the future. It is feasible to conduct a hearing conservation program with junior high school and senior high school students, and it appears possible to persuade teen-agers to protect themselves from exposure to loud noise while working on a farm.     

Is the gap more than gender? A longitudinal analysis of gender, gender role orientation, and earnings.

This study investigated the relationships among gender, gender role orientation (i.e., attitudes toward the gendered separation of roles at work and at home), and earnings. A multilevel model was conceptualized in which gender role orientation and earnings were within-individual variables that fluctuate over time (although predictors of between-individual differences in gender role orientation were also considered). Results indicated that whereas traditional gender role orientation was positively related to earnings, gender significantly predicted the slope of this relationship: Traditional gender role orientation was strongly positively associated with earnings for men; it was slightly negatively associated with earnings for women. Occupational segregation partly explained these gender differences. Overall, the results suggest that although gender role attitudes are becoming less traditional for men and for women, traditional gender role orientation continues to exacerbate the gender wage gap.

Sex differences in drug use by over 75-year-old persons at home: an epidemiologic study in Bern

The purpose of this study was to explore gender differences of medication use in a random sample of community-dwelling elderly subjects (N = 791). The average number of different medications in women (N = 578) was higher than in men (N = 213) (4.0 vs. 3.5, age corrected ratio 1.2, 95% confidence interval, 1.0-1.3). However, despite this relatively small difference in number of medications there was a major gender difference in the pattern of medications used. Compared to men, women had a higher use of benzodiazepines (risk ratio 1.7, 95% confidence interval, 1.3-2.3), diuretics (1.5, 1.1-2.0), nonsteroidal antiinflammatory agents (1.7, 1.2-2.3), and anti-depressants (2.5, 1.1-5.5), but a lower use of pulmonary (0.5, 0.3-0.9) and gout medications (0.2, 0.1-0.6). These gender differences in medication use can be explained by the fact that compared to men, women have a higher prevalence of non-lethal chronic conditions such as degenerative joint disease and hypertension. However, additional factors such as gender-specific differences in patient or physician behavior are likely to contribute to the observed differences in medication use as well. Overall, 36% of all women and 21% of all men were using benzodiazepines, with 42% of these subjects using long-acting compounds. Furthermore, 24% of all women and 15% of all men reported use of nonsteroidal antiinflammatory agents for which safer medication and non-medication alternatives would be available in many cases. Thus, women had a higher risk of inappropriate medication use than men. On the other hand, the finding that antidepressant use was 3% in men and 7% in women indicates that compared to women, men might be at increased risk for undertreatment of depression. Further causal evaluation of gender differences in both medication use and patient-physician interaction might contribute to detection and reduction of inappropriate drug use in older persons.     

Differential transitions between cocaine use and abstinence for men and women.

The longitudinal course of cocaine dependence is characterized by alternating periods of abstinence and relapse. Although gender has emerged as an important predictor of relapse, previous studies have examined mean differences in use by gender. Focusing strictly on differences in averages between men and women does not address potential gender differences in transitions between use and abstinence. Transition rates for men and women were compared using data from the National Institute on Drug Abuse Collaborative Cocaine Treatment Study. Abstinence and nonabstinence for each of the 6 months of active treatment was determined by using a composite measure of use that incorporated information from weekly and monthly self-reports and urine toxicology screenings. Random effects were introduced to describe intersubject heterogeneity in transition rates. In this sample of 454 patients, rates of transition between abstinence and use were significantly different between men and women, with men showing twice the rate of transition between states despite similar average levels of use. These data may have important implications for both treatment planning and the types of outcomes considered in clinical practice and research.

Differences in receipt of rehabilitation by impaired midlife men and women.

This analysis used data from the 1978 Survey of Disability and Work to assess gender differences in the receipt of rehabilitation services. The findings point to a continuing puzzle: Approximately equal proportions of impaired men and women received rehabilitation services; yet even when age, work history, severity of impairment, and receipt of disability insurance or workers' compensation were controlled for, a larger proportion of men than women were in the labor force after rehabilitation. Men were more likely than women to receive employment-related rehabilitation services. Furthermore, prediction of the receipt of rehabilitation services was poorer for women than for men. Variables hypothesized to predict receipt of rehabilitation were significant predictors for men, but not for women (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluation of problem solving and communication skills of persons with schizophrenia

This study examined gender differences in 162 female and 65 male patients with cancer referred to home care. Data were collected before hospital discharge using the Multidimensional Functional Assessment Questionnaire, the Karnofsky Performance Status, and the Quality of Life-Cancer Scale. Controlling for age and stage of disease, the results showed that men reported significantly more cancer-related impairments, more limitations in activity of daily living, and poorer social resources than women. No gender differences were found in quality of life, perceived emotional health, perceived physical health, performance status, and comorbidity. Significant predictors of self-care activities were: for women perceived physical health, Karnofsky Performance Status, and stage of disease (58% variance explained); for men Karnofsky Performance Status and medication taken (67% variance explained). Gender differences should be considered in discharge planning to provide appropriate home care services for male and female patients with cancer.     

The Troms? Study: frequency and predicting factors of analgesic drug use in a free-living population (12-56 years)

In a cross-sectional survey carried out in Troms? in 1986-7, 19,137 men and women aged 12-56 years from the general population were asked about their use of drugs during the preceding 14 days. Use of analgesics was very common. On average 28% of the women and 13% of the men had used analgesics. Drug use due to menstruation discomfort contributed only partly to the gender difference. Drug use was independent of age from 20 years of age. Factors having an impact on analgesic drug use were analyzed by logistic regression. The most significant predictors of analgesic use were suffering from headache (OR = 14.2(women) OR = 24.4(men)) and infections (OR = 2.0(women) OR = 2.4(men)). Drug users also tended to suffer from symptoms of depression (women) and sleeplessness (men). Lifestyle and sociodemographic factors were also significant predictors, but were of marginal importance (OR < 1.5) compared with occurrence of pain and infections.     

A pharmacokinetic-pharmacodynamic model of d-sotalol Q-Tc prolongation during intravenous administration to healthy subjects

The objective of this study was to assess the pharmacokinetics and pharmacodynamics of the dextro (d-) isomer of sotalol, a class III antiarrhythmic agent, in healthy young men and women after a single intravenous bolus dose. The design was open-label, randomized, parallel group. Each group (4 men and 4 women) received either 0.5, 1.5, or 3.0 mg/kg d-sotalol as an intravenous infusion for 2 minutes. Serial measurements of the d-sotalol plasma concentration and the Q-Tc interval data were recorded before, during, and for 72 hours after drug administration. The pharmacokinetics of d-sotalol were found to be well described by a three-compartment model with linear elimination clearance from the central compartment. There were no significant differences in the elimination clearance or volume of the central compartment between dose levels or between men and women. However, women were found to have a lower steady-state volume of distribution than men (1.20 L/Kg versus 1.43 L/Kg). The Q-Tc versus d-sotalol plasma concentration data were fitted to a model that assumed a distinct "effect compartment" and sigmoidal Emax response. The baseline Q-Tc, determined from the fittings, was found to be significantly higher in women (0.40 versus 0.38 seconds). The effect compartment clearance was found to be highly variable, with a median of 12.3 (range, 0.2-671,300) L/h. There were statistically significant differences in the effect compartment clearance by dose among men and by gender at a dose of 1.5 mg/kg. There were no significant differences detected between dose groups or genders for the d-sotalol effect site concentration at one half the maximum Q-Tc prolongation from baseline (EC50), EMAX, (the maximum Q-Tc prolongation from baseline) or the Hill coefficient. In conclusion, the pharmacokinetics of d-sotalol after intravenous administration are independent of dose and gender, because the difference between men and women in volume of distribution at steady-state is not clinically significant. The pharmacodynamics of Q-Tc prolongation produced by d-sotalol appear to be independent of dose and gender; however, there is considerable variability in the time course of effects on Q-Tc between individuals.     

Gender differences in acute alcohol effects on self-regulation of arousal in response to emotional and alcohol-related picture cues.

Basic mechanisms through which men and women self-regulate arousal have received little attention in human experimental addiction research, although stress-response-dampening and craving theories suggest an important role of emotional arousal in motivating alcohol use. This study examined gender differences in the effects of acute alcohol intoxication on psychophysiological and self-reported arousal in response to emotionally negative, positive, and neutral, and alcohol-related, picture cues. Thirty-six social drinkers (16 women) were randomly assigned to an alcohol, placebo, or control beverage group and exposed to picture cues every 10 s (0.1 Hz presentation frequency). Psychophysiological arousal was assessed via a 0.1-Hz heart rate variability (HRV) index. A statistically significant beverage group-by-gender interaction effect on psychophysiological, but not self-reported, arousal was found. The 0.1-Hz HRV responses to picture cues were suppressed by alcohol only in men. This gender-specific suppression pattern did not differ significantly across picture cue types. There were no significant gender differences in the placebo or control group. Greater dampening of arousal by alcohol intoxication in men, compared with women, may contribute to men’s greater tendency to use alcohol to cope with stress.

Intimate justice: confronting issues of accountability, respect, and freedom in treatment for abuse and violence

Comparisons of nationally representative survey data of the population ages 18-54 years in 1971 (N = 2252) and 1992 (N = 1718) from Finland show that sexual satisfaction has greatly increased particularly among women. Some predictors of sexual satisfaction of men and women are examined on the basis of the 1992 survey data on people ages 18-74 years (N = 2250). Correlations between social background factors, sexual ideas and assertiveness, optional relationships, sexual practices, organism, and satisfaction with sexual intercourse were calculated. To control the simultaneous effect of the variables explaining satisfaction, path analyses were conducted. Results show that young age, a sexually unreserved and a nonreligious childhood home, early start of sexual life, high education, sexual assertiveness, considering sexuality important in life, reciprocal feeling of love, use of sex materials, frequent intercourse, many-sided (versatile) sexual techniques, and frequent orgasm correlate with finding sexual intercourse pleasurable. There were some gender differences in the connections between the independent factors and satisfaction with coitus. The importance of sexuality in life, love, and the use of sexual materials were connected directly to physical sexual satisfaction among men but only indirectly among women. For women, but not for men, young age and early start of sexual life correlated with enjoyment of intercourse. The greater sexual dissatisfaction of women compared to men, which still prevails, may be due to their late start of sexual life, conservative sexual attitudes, unimportance of sexuality in life, lack of sexual assertiveness, and use of restricted sexual techniques. The emancipation of women may change these ideas and practices of women. This might lessen the gender gap in physical sexual satisfaction.     

Heart rate variability and heart rate in healthy volunteers. Is the female autonomic nervous system cardioprotective?

AIMS: Heart rate variability has been proposed as an indicator of cardiovascular health. Since women have a lower cardiovascular risk, we hypothesized that there are gender differences in autonomic modulation. METHODS AND RESULTS: In 276 healthy subjects (135 women, 141 men) between 18 and 71 years of age, 24 h heart rate and heart rate variability were determined. All heart rate variability parameters, except for pNN50 and high frequency power, were higher in men. After adjustment for heart rate, we obtained gender differences for: the standard deviation (P=0.049), the standard deviation of the 5 min average (P=0.047), low frequency power (absolute values, P=0.002; normalized units, P<0.001) and ratio low frequency/high frequency (P<0.001). There were no significant gender differences in heart rate variability parameters denoting vagal modulation. Gender differences were confined to age categories of less than 40 years of age. The majority of heart rate variability parameters decreased with age. Only in men, was a higher body mass index associated with a higher heart rate and with lower heart rate variability parameters (P<0.001). CONCLUSION: Cardiac autonomic modulation as determined by heart rate variability, is significantly lower in healthy women compared to healthy men. We hypothesize that this apparently paradoxical finding may be explained by lower sympathetic activity (low frequency power) in women. This may provide protection against arrhythmias and against the development of coronary heart disease.     

Coping and distress in organizations: The role of gender in work stress.

This article investigates the positive value of women's interpersonal way of coping by examining coping benefits on distress depending on gender socialization in the Spanish cultural context. The participants were 332 men and 129 women employed by financial companies. Preliminary results showed that women used social support coping more frequently than men, whereas there were no gender differences in the use of direct action coping. Interactive effects of gender in the relationship between coping strategies and distress and psychosomatic complaints were found; social support coping was only beneficial for women, whereas direct action coping was more beneficial for men than for women. Implications of these results and their significance within the framework of national and sector cultures are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stressful life events, gender, and substance use: An application of tobit regression.

Extended research on stressful life events (SLEs) and substance use by examining gender differences in the relationship between SLEs and the use of 4 substances, determining whether SLEs were uniquely related to each type of substance use, and using tobit regression analysis to increase statistical conclusion validity. Data were obtained from 606 men and 1,001 women (all Ss aged 19–65 yrs) who were interviewed and responded to a questionnaire. Analyses revealed that the magnitude of the positive relationship between SLEs and cigarette use did not differ across men and women, whereas SLEs were unrelated to illicit drug use among both men and women. In contrast, SLEs were more strongly related to alcohol use among men, whereas they were more strongly related to psychotherapeutic drug use among women.

Hearing in advanced age. A study of presbyacusis in 85-, 88- and 90-year-old people

Hearing in elderly people was investigated in an epidemiological longitudinal study (H70) encompassing a cohort representative of an urban Swedish population born in 1901-02. The participants in the study were followed audiometrically over a 20-year period from 70 to 90 years of age. This study focused on hearing and its decline during the later time span in which the participants were tested at the age of 85, 88 and 90 years. The results revealed that hearing loss in advanced age progressed only slightly in both men and women. The annual hearing threshold decline was about twice as large in the eighth decade of life as compared with the ninth. Hearing function was similar in the respondents tested at the out-patient clinic and in those tested at home. There were no consistent indications that survivors to a great age showed better hearing at entry to the study at 70 years of age. Some gender differences were found and are discussed.     

Aging and high-frequency hearing sensitivity

As part of a large population-based study of hearing and aging, ultra high-frequency (9-20 kHz) threshold measures are reported for 3396 participants grouped by age (48-59 years, n = 1233; 60-69 years, n = 1031; 70-79 years, n = 851; 80-92 years, n = 281). Ultra high-frequency (UHF) thresholds were higher for older age groups. The percentage of unmeasurable responses also was significantly higher for older age groups and for higher frequencies in the UHF range. The observed age effects remained significant after adjusting for gender. In general, UHF thresholds were significantly higher for men compared to those for women at lower UHF frequencies (9-14 kHz), but were not significantly different by gender for the highest UHF frequencies (16, 18, and 20 kHz). After accounting for hearing loss at traditional audiometric frequencies (250-8000 Hz), the age effect still remained; even for comparable degrees of sensorineural hearing loss, participants in older age groups evidenced higher UHF thresholds.     

Type of items and the magnitude of gender differences on the Mental Rotations Test.

The present study considered the structure of the drawings used in the Mental Rotations Test (MRT) to examine whether distractors that are either a mirror image or structurally different from the target as well as response alternatives with occluded and nonoccluded parts affect the magnitude of gender differences on this test. One hundred and three women and 100 men undergraduate students were given unlimited time to complete the MRT. A gender by occlusion interaction on correct responses showed that gender differences were larger for occluded than for nonoccluded items. Examination of performance as a function of item placement in the test suggested that it is unlikely that the results could be accounted for by differential practice effects in women and men. Implications of these results for explanations of gender differences on the MRT and for the training of spatial abilities are discussed.

Gender differences in insulin-like growth factor and bone mineral density association in old age: the Rancho Bernardo Study

Insulin-like growth factor-I (IGF-I) clearly plays a role in bone metabolism and maintenance, as evidenced by in vitro and animal studies. In clinical studies, the age-related decrease in IGF-I parallels the age-related decrease in bone mineral density (BMD), but several age-adjusted cross-sectional studies show no consistent association of IGF-I and BMD. We report here a cross-sectional study of serum IGF-I and BMD levels in 483 men and 455 postmenopausal women not using estrogen; subjects were 55 years of age and older, community-dwelling, ambulatory, and unselected for bone density. IGF-I was measured by a highly specific radioimmunoassay. BMD was measured at the lumbar spine and hip using dual-energy X-ray absorptiometry. Men had higher IGF-I and BMD levels than women. In age-adjusted and age-stratified models, IGF-I was associated with BMD only in women (test for interaction, p < 0.0001). Gender differences persisted in gender-specific multiple regression analyses adjusted for age, body mass index, thiazide diuretic use, current smoking, alcohol intake, physical activity, and weight change; IGF-I was significantly associated with BMD at the spine (p = 0.0001) and hip (p = 0.02) in women, but not in men (p's > 0.6). Circulating estradiol levels were not associated with IGF-I levels in either gender, testosterone was inversely associated with IGF-I and only in men. This striking gender difference has not been described previously. Its etiology is unknown. The answer could lead to improved understanding of gender differences in osteoporosis and in response to treatment with IGF-I or growth hormone.
