Effects of ethnic, age, and bereavement on complete denture patients.

Geriatric patients in prosthodontics require neverending patience and a unique consideration of the "healing" concept. Old people may act helplessly and hopelessly, and even though they are cooperative during treatment, they may lack the capacity to verbalize their distress. The dentist must look for unspoken clues instead, keeping an eye open for various possible factors which might explain a patient's behavior. Many elderly people have experienced the loss of a spouse or other relative. Usually such experiences are associated with increased rate of disease and death and certainly qualify as a severe psychological trauma. Because the effects of bereavement in the prosthodontic patient are often inconspicuous, they pose a diagnostic challenge. The most important direct conclusion to be drawn from this study is the overwhelming importance of patients' ethnoclutural background which shapes the basic characteristics of their response. People of Oriental origin tended to increase their (indirect) expression of emotional distress after bereavement, while Ashkenazis reacted to bereavement with decreasing complaints. Maximum results can be attained in treating prosthodontic patients when their ethnocultural and socioeconomic behavioral determinants of their therapeutic response are based upon these data.

Gender differences in structural and behavioral determinants of health: an analysis of the social production of health.

This paper explores aspects of the social production of health by focussing on the ways in which levels of health are shaped by structures of social inequality and behaviors or 'lifestyles'. We address two questions: What is the relative importance of the social, structural and behavioral determinants of health? And, are there gender differences in the determinants of health? These questions are explored using multiple regression analyses of data from the 1994 Canadian National Population Health Survey. Two measures of health are used: subjective health status and the Health Utilities Index (a measure of functional health status). By structural determinants we refer to age, family structure, main activity, education, occupation, income and social support. Behavioral determinants include lifestyle factors related to smoking, drinking, weight and physical activity. Findings indicate that the structures of social inequality are the most important determinants of health acting both independently and through their influence on the behavioral determinants of health. There are very real differences in the factors that predict women's and men's health. For women, social structural factors appear to play a more important role in determining health. Being in the highest income category, working full-time and caring for a family and having social support are more important predictors of good health for women than men. Smoking and alcohol consumption are more important determinants of health status for men than women, while body weight and being physically inactive are more important for women than men. Our findings suggest the value of models which include a wide range of structural and behavioral variables and affirm the importance of looking more closely at gender differences in the determinants of health.

Factors associated with Hispanic women's HIV-related communication and condom use with male partners.

To determine factors influencing Hispanic women's HIV-related communication and condom use with their primary male partner, 189 Dominican, Puerto Rican, and Mexican women were interviewed regarding sexual behaviour and condom use, relationship characteristics, perceived risk for HIV, and HIV-related communication with the primary male partner. Level of HIV-related communication with the primary male partner was associated with the woman's perceived risk for HIV and her rating of the openness with which she could communicate with her primary partner. Mexican women were less likely than Puerto Rican or Dominican women and women with multiple partners were less likely than those with one partner to communicate about HIV-related issues with their primary partner. Women reporting more condom use with their primary partner were younger, had discussed HIV-related issues more with the primary partner, and were less likely to expect negative reactions to requests for condom use than those reporting less condom use. These results suggest that prevention programmes that increase both general and HIV-specific communication between members of a couple may facilitate safer sex practices by the couple. Prevention programmes that encourage women to insist on condom use should consider the woman's expectations about her partner's reaction as a potential barrier to the initiation of safer sex practices.

Risk factors for intravenous drug use and sharing equipment among young male drug users in Longchuan County, south-west China.

OBJECTIVES: To identify the risk factors for intravenous drug use and sharing of equipment in Longchuan County in south-west China. METHODS: Demographic information and sexual and drug-use-related behavior between 1 January 1991 and 1 August 1994 were collected retrospectively from a cohort of young male drug users aged 18-29 years in 82 villages. RESULTS: A total of 433 drug users were identified. The cumulative incidence of intravenous drug use was 40.0% during the 3.7-year study period. The annual incidence increased from 10% in 1991 to over 30% in 1994. Risk factors for intravenous drug use among drug users, according to the multivariate model, included having had premarital/extramarital sex [odds ratio (OR), 1.5; 95% confidence interval (CI), 1.01-2.3], having a family member who used drugs in 1991 (OR, 1.8; 95% CI, 1.1-2.9), and currently not married (OR, 1.6; 95% CI, 0.98-2.7). Being Buddhist protected against intravenous drug use (OR, 0.4; 95% CI, 0.2-0.9). The population attributable fraction was 30% for not being currently married, 17% for having had premarital/extramarital sex and 14% for having a family member who used drugs. The risk factor for sharing of equipment was being of Jingpo ethnicity (OR, 5.8; 95% CI, 2.5-13.8). The average incidence of sharing equipment was 19.6% per year. The population attributable fraction for sharing equipment was 58.5% for being Jingpo. CONCLUSIONS: The incidence of intravenous drug use and sharing equipment is increasing. Therefore, it is urgent that vigorous, effective intervention programs be initiated in southern Yunnan. Unmarried, sexually promiscuous Jingpo drug users with a family history of drug use should be especially targeted. Given the problems of transport and communication in this remote area of China, intervention programs which use existing social, governmental and community networks should be implemented.

Crack, sex, and STD.

Increasing rates of syphilis, gonorrhea, chancroid, and sexually transmitted human immunodeficiency virus infection appear to be related to crack cocaine use. This article critically reviews 16 epidemiologic studies that examine drug use, sexual behavior, and sexually transmitted disease (STD). Eight studies found an association between crack and STD, one study found no association between crack and STD, and seven studies found STD to be related to other drugs or methods of cocaine use. The exchange of sex for money or drugs was associated with STD in seven studies. Publications that were reviewed have numerous methodologic weaknesses: broader sampling, uninfected comparison groups, and greater specification of drug use and sexual risk behaviors are needed. Further research should compare different drugs and associated sexual behavior and STD to assess the unique risk conferred by crack. Designing effective interventions will require investigation of risk behavior determinants and barriers to health care.

Adolescents and sexually transmitted diseases.

Sexually transmitted diseases (STDs) are a serious health problem for adolescents, occurring in an estimated one-quarter of sexually active teen-agers. Many of the health problems--including STDs--result from specific risk-taking behaviors. Determinants of STD risks among adolescents include behavioral, psychological, social, biological, institutional factors. Education is an important component in STD control in adolescents. The goal of education is to increase adolescent self-efficiency in practicing STD prevention and risk-reduction. A comprehensive approach including quality, theory-based education, accessible and effective health clinics, and improved social and economic conditions has the most promise of controlling STDs in adolescents.

Newborn dopamine-beta-hydroxylase, minor physical anomalies, and infant temperament.

The authors examined newborn anomaly scores for 193 normal infants in relation to obstetrical history, newborn dopamine-beta-hydroxylase (DBH), and 5-month (N=185) and 1-year (N=123) infant behavior, determined by a questionnaire completed by their mothers. There was no significant relationship between anomaly score and obstetrical history or 5-month infant temperament; low significant correlations were found between newborn DBH and 1) infant irritability and unsociable response and 2) 1-year anomaly scores and reported activity levels. The authors discuss the possible importance of these findings.

Socio-behavioral determinants of oral hygiene practices among USA ethnic and age groups.

In this study, socio-behavioral determinants of oral hygiene practices were examined across several dentate ethnic and age groups. Oral hygiene scale scores were constructed from toothbrushing and dental floss frequencies self-reported by population-based samples of middle-aged (35-44 years) and older (65-74 years) dentate adults representing Baltimore African-American and White, San Antonio Hispanic and non-Hispanic White, and Navajo and Lakota Native American persons participating in the WHO International Collaborative Study of Oral Health Outcomes (ICS-II) survey. Female gender, education, certain oral health beliefs, household income, and the presence of a usual source of care were revealed with multivariate analysis to show a significant positive relationship with higher oral hygiene scale scores (indicating better personal oral hygiene practices). Other socio-behavioral variables exhibited a more varied, ethnic-specific pattern of association with oral hygiene scale scores.

Determinants of high-risk sexual behaviour and condom use among adults in the Arusha region, Tanzania.

Determinants of multiple sexual partners and condom use among adults were assessed through a population-based survey in one urban, one semi-urban and one rural community in the Arusha region, northern Tanzania. The study samples were obtained by randomly selecting clusters of 10 households from the 3 communities. Informed verbal consent was sought from each respondent for participation in the study. High-risk sexual behaviours and condom use were assessed using a structured questionnaire. It was observed that significantly more men than women reported having multiple sexual partners (49% vs 25.2%; OR = 1.69; 95% CI = 1.51-1.90) and urban men were significantly more likely to report having multiple sexual partners than men in rural areas. In both men and women, early sexual debut was associated with having multiple sexual partners while travel, alcohol use, and sex under the influence of alcohol were significantly associated with multiple sexual partners in men only. AIDS-related discussion was significantly associated with having fewer sexual partners in both men and women. Of the 1551 respondents, 320 (20.6%) reported having ever used a condom and of the 320 respondents who had ever used a condom, 34 (10.6%) reported having used it at the last sexual intercourse. Significantly more men than women reported having ever used a condom (34.1% vs 14.1%; OR = 1.77; 95% CI = 1.56-2.01). In both men and women, early sexual debut and being young, unmarried, travelling out of the Arusha region and having multiple sexual partners were associated with increased condom use. For both men and women, frequent discussion of AIDS with family members or friends was associated with increased condom use. These data suggest that interventions targeting adolescents and young adults may be effective for control of HIV transmission in Tanzania. In particular, creation of opportunities for people to come together and discuss AIDS might be an important strategy.

Factors associated with condom use in the male population of Mexico City.

Sexually transmitted diseases (STDs) are an important public health problem, due to their medical, social and economic repercussions. Therefore, more knowledge is needed about the sexual behaviour that promotes their spread, in order to improve control and prevention strategies. Our aim was to determine the frequency of male condom use associated with sexual behaviour factors, a history of and knowledge about STDs in a sample of the male population in Mexico City. During 1994 a cross-sectional epidemiological study was carried out, using multi-stage sampling with conglomerates, in 1377 men from 15 to 49 years old. The mean age was 34.5 years (SD 7.5 years). Mean age at first sexual relations was 17.7 years (SD 2.8 years). The global proportion of condom use during the last sexual relation was 24.6%; use according to type of female sex partner in the last year was 18.8% with regular partners and 62.5% with occasional partners. The principal predictors of male condom use, identified through statistical modelling, were: younger age (<25 years), middle and high education level (>9 years), middle and high socioeconomic level and type of sexual partners (occasional and regular). This population has risk factors for acquiring and transmitting some STDs, such as occasional sexual partners and a history of STDs. Characteristics which are important in relation to male condom use were identified, such as age (younger than 35), education (complete junior high school or more) and type of sexual partners (occasional and regular).

Is homosexuality hormonally determined?

This paper suggest there is insufficient evidence to conclude that homosexuality has endocrine bases. The search for hormonal correlates occurs within a model that views homosexuality as a medical problem requiring biological explanations and a program of treatment or prevention. This search is heavily rooted in popular conceptions of gender-appropriate behavior, as well as in naive concepts of the significance of hormonal changes. Two kinds of hormonal study are considered here. Researchers may either (a) investigate hormone levels in adult populations or (b) investigate hypotheses of behavioral determination by prenatal hormones. Much of the latter information derives from animal studies, commonly on the laboratory rat. This paper questions the validity of assumptions underlying these studies--assumptions about the behavior of the laboratory rat itself and, more importantly, about the legitimacy of this animal as a model for human behavior. It is suggested that, although such hypotheses are naive, their current popularity arises from their potential role in "controlling" homosexuality.

The effect of tailoring a model HIV prevention program for local adolescent target audiences.

In five U.S. sites (Nashville, Tennessee; Newark, New Jersey; northern Virginia; Phoenix, Arizona; and Sacramento, California), HIV risk-reduction workshops were mounted as a part of the Prevention Marketing Initiative (PMI). In four of the five sites, the workshop curriculum was a version of Be Proud! Be Responsible! (Jemmott, Jemmott, & McCaffree, 1996) that had been tailored to fit the needs of local target audiences. This article describes the evaluation of the PMI workshops. Protective effects on several behavioral determinants and behavioral outcome measures were observed 1 month after the workshops. Based on the overall pattern of results, it was concluded that the PMI workshops reduced the likelihood of unprotected sex among participants. The intervention developed by Jemmott and colleagues appears to have retained its effectiveness after it was tailored to meet perceived local needs.

Demographic and behavioral determinants of the reduction of male-to-female birth ratio in Spain from 1981 to 1997.

The ratio of male-to-female births has been declining in Spain since 1981. In the last few decades, the proportion of male newborns has also been decreasing in other industrialized countries. It has been hypothesized that these declines are due to environmental factors such as a longer exposure to environmental pollutants, hormonal levels, or sexual behavior. The objective of this study was to examine the evidence of decline in the male proportion of births in Spain and to correlate it to demographic causes (mother's age, marriage age, and age difference between husband and wife). The analysis was based on birth records in Spain from 1945 to 1997. The data show a significant correlation (p < 0.01) between the reduction in the ratio of male-to-female births observed and two variables, the variations in mean age at marriage and the older age at which women give birth. More women are delaying childbearing until their thirties and, as a consequence, there has been a decrease in the proportion of male newborns.

Physical activity and bone development during childhood and adolescence. Implications for the prevention of osteoporosis.

Osteoporotic fractures are a debilitating and a frequently fatal health problem for older adults. A growing body of evidence indicates that osteoporosis has its origin in early life and that the level of development of bone mass during childhood and adolescence strongly influences the risk for osteoporotic fractures. The development of osteoporosis results from an interaction between 1) bone mass accrual via growth, remodeling, and modeling during childhood and adolescence and 2) the maintenance of bone mass (primarily via remodeling) during adulthood. Peak bone mass which occurs at the conclusion of growth may be the most important factor for preventing osteoporosis since as much bone is accrued during the adolescent years as most individuals will lose during all of adult life. In this review, I examine the contribution of physical activity as an important behavioral determinant of children's bone development, particularly of peak bone mass. Since it is a behavior, physical activity is a potentially modifiable determinant of peak bone mass; therefore, understanding activity's impact on bone health is central to developing primary prevention strategies for osteoporosis.

Condom knowledge, attitudes and use among patients attending the public STD clinic in Singapore.

Three hundred patients (255 males and 45 females) attending the public STD clinic in Singapore were interviewed regarding their frequency of condom use, attitudes towards condoms, problems related to condom use and places of purchase of the condoms. Among respondents with regular partners, 55.2% of males and 48.8% of females never used condoms, only 12.4% of males and 16.3% of females used condoms consistently. Among respondents with non-regular partners, only 2.2% of males used condoms consistently. The commonest reasons why male respondents did not use condoms consistently were that condoms decreased sensation, condoms made sex mechanical, the use of other forms of contraception, no condoms were available, and the perception that there was no risk of contracting STD/AIDS. Condoms were most commonly obtained from sex partners, supermarkets, roadside sundry shops and the Maternal & Child Health Clinics (MCHCs). About 8% of both males and females had experienced some problems with condoms before. Greater efforts to promote the practice of protected intercourse among the STD patient population as well as in the general population are required in order to control the spread of STD and AIDS in Singapore.

AIDS-relevant condom use by gay and bisexual men: the role of person variables and the interpersonal situation.

This study examined the relative ability of selected person variables (interpersonal self-efficacy, self-control, attitudes about the effect of condoms on sex, normative beliefs) and interpersonal-situational variables (partner preference, partner serostatus) to explain gay and bisexual males' (N = 267) condom use during insertive and receptive intercourse. Partner preference accounted for a large amount of variance in condom use by itself and when controlling for the effects of the remaining variables. Exploratory hierarchical regression analyses suggested that the receptive partner's preference influenced condom use decisions to a greater extent than did the insertive partner's. Partner serostatus alone explained little variance in condom use. However, partners serostatus interacted with subject serostatus such that dyads with concordance serostatus (i.e., both partners HIV positive or both HIV negative) used condoms the least, and dyads with discordant serostatus used condoms the most. Results suggest that the interpersonal situation plays an important role in condom use decisions.

Factors related to condom use with casual partners among urban African-American and Hispanic males.

Constructs from the Health Belief Model and the Theory of Reasoned Action were tested for their relationship to condom use with casual partners in a probability sample of urban African-American and Hispanic males aged 15-24. The results indicate the importance of 1) promoting a sense of male responsibility regarding condom use; 2) promoting the belief that condoms should be used with all partners; 3) developing skills for condom use and partner communication; and 4) increasing perceived susceptibility to HIV infection in design of intervention programs.

Non-condom use among female nurses in Zambia.

OBJECTIVES: To estimate non-condom user rate and to characterize non-condom users among female nurses. DESIGN: Cross sectional. SETTING: Health institutions. SUBJECTS: Data from 640 (86.5pc) out of 740 consenting female nurses were available for analyses. MAIN OUTCOME MEASURE: Non-condom user rate. RESULTS: Non-condom user rate (per 100) among the female nurses was 73.1pc (95pc CI69.7 to 76.5). Non-condom users tended to be aged above 30 years (OR 1.57; 95pc CI 1.02 to 2.40), midwives (OR 1.56; 95pc CI 1.03 to 2.37), married (OR 2.70; 95pc CI 1.73 to 4.21), not to think that spouse/partner has had sex with other partners (OR 1.72; 95pc CI 1.11 to 2.68) and to have had a sexually transmitted disease (OR 2.61; 95pc CI 1.25 to 5.43). CONCLUSION: There was a surprising high level of non-condom users among female nurses, probably due to the inability for females to initiate or negotiate condom use.
