Current models of nicotine dependence: what is known and what is needed to advance understanding of tobacco etiology among youth.

Youth smoking has risen dramatically during the last 5 years, leading one to the conclusion that prevention interventions have not been particularly effective. This paper provides an examination of features that define adult nicotine dependence and argues that these features need to be considered in any studied examination of youth etiology and development to nicotine dependence. We review the historical context for the concept of nicotine dependence, features that define the concept and current models of substance dependence more generally. Recommendations for future research are provided.

Social factors influencing the acquisition of antibiotics without prescription in Kerala State, south India.

We investigated the magnitude of self-medication with antibiotics in a peri-urban area of Southern Kerala State, India and factors influencing this practice. First, a random sample of 400 households was surveyed in one primary health centre area near Trivandrum. We found 69.3% (95% CI = 64.8-73.8) of households had at least one person using a pharmaceutical product during the two-week recall period; antibiotics formed almost 11% of the medicines consumed. Next, pharmacy based interview and observation data were collected from 405 antibiotic purchasers sampled from 11 out of the 12 private pharmacies in the area. Seventy-three of these 405 customers purchased antibiotics without a prescription (18%; 95% CI = 14.3-21.7). By combining the household survey and pharmacy observations, we estimate that almost half of 1% (0.41%; 95% CI = 0.24-1.16) of the population, or four people per 1000, is engaged in self-medication using antibiotics in Kerala in any two-week period. Our data show that people least likely to follow this practice are from higher income families, having more education and higher status occupations and receiving the benefits of medical insurance. Conversely, logistic regression analysis indicated that risk of buying antibiotics without a script was associated with education at secondary level or below, the perception that it is expensive to consult a doctor and low satisfaction with medical practitioners. Keralites' self-medication patterns are interpreted broadly using social, cultural, historical and economic perspectives. Solutions to the problem of antibiotic misuse are suggested, proceeding on several fronts: among practitioners, suppliers and marketeers of medicines, and among the population of pharmaceutical consumers themselves.

Contamination of medicine injection paraphernalia used by registered medical practitioners in south India: an ethnographic study.

While considerable attention has been directed at the important role of intravenous drug use in the spread of human immunodeficiency virus (HIV) and hepatitis B, little research to date has been conducted on the role of medicine injections in disease transmission. This is the case despite the fact that (a) the number of medicine injections is several orders of magnitude greater than injections of illegal drugs and (b) the networks of people potentially affected by contaminated medicine injection paraphernalia is far wider. In this article we examine the medicine injecting practices of a random sample of 40 registered medical practitioners (RMP) who have not had formal training in allopathic medicine (do not have MBBS or MD degrees) in Tamil Nadu, India. Attention is drawn to: (a) the lack of vigilance practitioners exercise in maintaining hygienic needles and syringes, (b) their perceptions of what constitutes acceptable hygienic procedure and (c) how patients respond in contexts where they are able to purchase disposable needles and syringes directly from practitioners or from the open market prior to visiting a practitioner. Study results are a cause for alarm and indicate widespread contamination of injection paraphernalia as well as common reuse of disposable needles. The study was confined to RMPs and the researchers strongly suggest that future studies of MBBS trained doctors practising in the public and private sectors be carried out. A structured observation instrument developed to record needle and syringe contamination during the process of injection administration is provided.

Developing an interactive STD-prevention program for youth: lessons from a north Indian slum.

An intervention developed to teach young men in the urban slums of Lucknow, India, about sexually transmitted diseases is described in detail. This community-based intervention was designed to impart core educational messages and to address preexisting ideas about sexual health and STD-prevention practices among participants. Indicators of knowledge recorded before and after the intervention are presented and evaluated against the scores of a control group. Levels of sexual activity and factors associated with risky sex are discussed. The intervention was successful in raising the young men's awareness of STDs significantly in all areas except for the length of time that symptoms take to manifest following risky sex and the ineffectiveness of washing one's genitals after sex to avoid acquiring STDs. Lessons learned during the intervention are described as a means of informing future STD-education programs, and issues requiring prompt attention are identified.

Women and tobacco: moving from policy to action.

A gender perspective contributes to a better understanding of the epidemiological trends, social marketing strategies, economic policies, and international actions relating to women and the tobacco epidemic. Evidence is provided in this article for the negative impact of tobacco use by women and of passive smoking on the health of women and children. Use of tobacco by women is increasing and this is related to the tobacco industry's aggressive advertising, sponsorship and promotion strategies. Policy directions are proposed in this article. At all levels, a multi-pronged strategy--including changes in legislation and fiscal policies, improvements in gender-sensitive health services, and cessation programmes--should be considered. Much more gender-specific research on tobacco use is needed, particularly in developing countries. Women's empowerment and leadership should be at the centre of all tobacco control efforts and are essential for the success of national programmes and the recently introduced Framework Convention on Tobacco Control.

Trial of a community-based intervention to decrease infestation of Aedes aegypti mosquitoes in cement washbasins in El Progreso, Honduras.

Washbasins and metal drums are important sources of Aedes aegypti mosquitoes in much of Latin America. When manual cleaning was found to be ineffective in eliminating mosquito larvae in a community-based control programme in El Progreso, Honduras, it was decided to develop and evaluate an improved method of removing mosquito eggs based on commonly-available materials. The method, named La Untadita ('The Little Dab', in English), consists of five steps: mixing chlorine bleach and detergent to make a paste, applying the mixture to the walls of the container, waiting 10 min, scrubbing with a brush, and finally rinsing with water. A field trial of the Untadita was conducted in 13 peri-urban neighbourhoods. At the first post-intervention survey, in spite of high levels of exposure to the community-based intervention, high levels of knowledge regarding the Untadita and high levels of its reported use, little or no impact was discernable on mosquito larvae and pupae. The method was then modified by increasing the recommended quantities of bleach and detergent and simplifying the instructions. In the second post-intervention survey, knowledge of the steps and their order increased further; the intervention neighbourhoods had significantly fewer algae on washbasin walls, an indicator of more effective cleaning; and numbers of pupae and 3rd and 4th instar larvae were significantly lower than in untreated neighbourhoods. Effective promotion of the Untadita should be able to control mosquito infestation in many washbasins, especially those in frequent use, thus reducing the need for chemical and biological larvicides that may be either more costly or less acceptable to householders.

Pharmacies, self-medication and pharmaceutical marketing in Bombay, India.

Studies of pharmaceutical practice have called attention to the role played by pharmacists and pharmacy attendants in fostering self-medication and medicine experimentation among the public. Left undocumented is the extent to which clients passively follow the advice of pharmacy personnel or question their motive or expertise. While research has focused on pharmacists and pharmacy attendants as agents encouraging self-medication and medicine experimentation, adequate attention has not been paid to pharmacist-client interactions that are sensitive to the social, cultural, and economic context in which medicine sales and advice occur. This paper highlights the context in which pharmacy attendants engage in "prescribing medicines" to the public in Bombay, India. An ethnographic description of pharmacies and pharmaceutical-related behavior in Bombay is provided to demonstrate how reciprocal relationships between pharmacy owners, medicine wholesalers and pharmaceutical sales representatives (medreps) influence the actions of pharmacy staff. Attention is focused on the role of the medicine marketing and distribution system in fostering prescription practice, pharmacy "counter-pushing" and self-medication. In documenting the profit motives of different players located on the drug sales continuum, it is argued that the economic rationale and the symbiotic relations that exist between doctors, medreps, medicine wholesalers and retailers, need to be more closely scrutinized by those advocating "rational drug use".

Changing patterns of pharmaceutical practice in the United States.

In the United States, contradictions related to medicine use abound in a social environment in which the pursuit of health has become a cultural project. In a marketplace where over half a million health products are available, choices at once seem to foster agency and encourage dependency on medical fixes. The aggressive marketing of medicines as indispensable commodities co-exits with rising concerns among the lay population about what is safe in the short- and long-term. In this paper we broadly consider medication-related practice in the United States as it is affected by social, cultural, and political-economic factors. We direct attention to changes in medicine use related to product proliferation, lowered thresholds of discomfort, the economics of health care, and a revival of the self-help ethic. We also consider the manner in which the demand for and use of medications reflect deeply embedded cultural ideals and emergent perceptions of need. We juxtapose two trends in American thinking about medicines: (1) the perception that "more is better," associated with cultural impatience with illness; and (2) a growing doubt about medicine necessity, safety, and efficacy.

Smoking experimentation and initiation among adolescent girls: qualitative and quantitative findings.

OBJECTIVE: To use qualitative and quantitative findings to describe patterns of smoking experimentation and initiation among adolescent girls. DESIGN: Ethnographic in-person interviews, focus groups, telephone interviews, and a survey questionnaire were used over a one-year period. The paper reports on cross-sectional data drawn from a three-year longitudinal study. SUBJECTS AND SETTING: 205 girls participated in the survey and interviews during year 3 of the study. Girls were drawn from two urban high schools in Tucson, Arizona (USA), and were in grades 10 and 11 (mean ages 16 and 17, respectively) during year 3. RESULTS: Overall, 30% (n = 61) of informants reported that they currently smoked, 7% (n = 15) were ex-smokers, and 63% (n = 129) were "non-smokers". The most frequently cited reasons for smoking were stress reduction and relaxation. Several stress-inducing situations, including family environment, social relations with classmates, and schoolwork, are discussed. The notion of peer pressure is re-examined in the light of teenagers' experience that there is little overt pressure to initiate smoking. Consonant with notions of adolescent autonomy, the theme of independence in smoking initiation and continuation permeated girls' narratives about their smoking behaviour. Girls projected the image that they could control their cigarettes rather than have their cigarettes control them. CONCLUSIONS: Smoking prevention and cessation programmes need to address and counter the smoking/relaxation association, which was identified as an important reason for smoking among adolescent girls. Questions typically used in surveys to measure smoking behaviour do not adequately define the smoking experience as described by teenagers.

Vaccinations in the Third World: a consideration of community demand.

Impressive increases in immunization rates have been reported in several less developed countries (LDCs) as a result of intensive EPI programs. An issue arises as to whether existing rates of immunization coverage can be sustained/increased given projected cutbacks in funding. This issue calls into question the assumption that as immunizable disease rates fall, local populations will need less encouragement to secure immunization services. This article considers how immunizations are perceived by lay populations and how perceptions of utility and need effect demand which in turn effects the sustainability of EPI programs. Among issues addressed is the observation that when specific diseases are not linked to specific immunizations, misimpressions related to the number of immunizations needed for "good health" abound. Also considered are metamedical reasons immunizations (and immunization programs) are both resisted and demanded in particular political contexts.

Dieting and "watching" behaviors among adolescent females: report of a multimethod study.

PURPOSE: This study posits a distinction between "watching what you eat" and dieting behaviors in a sample of adolescent females. Findings suggest that the dichotomy of dieter/nondieter fails to capture a range of healthful behaviors practiced by many adolescent girls. METHODS: Anthropologic and nutritional research methods were used in this study. Data were drawn from 1 year of a longitudinal study of food intake and dieting behaviors in a sample of 231 adolescent females. Multiple methods including one ethnographic interview, a survey questionnaire, a telephone interview, and food records were collected from each informant. RESULTS: Although 44% of the girls in this sample reported trying to lose weight on the day of the survey, only 8.6% of the food records reflected dieting days. In interviews, many identified "watching what they eat" as a health-promoting strategy that allowed them to maintain their weight. Analysis of food record data confirmed a trend toward higher intakes of micronutrients. CONCLUSIONS: Research concerned with adolescent weight loss behaviors has focused more on negative than positive health attitudes and behaviors. The present study identified the behavior of "watching" as distinct from dieting. "Watching" was widely utilized by girls in this sample as a way to maintain weight and promote health.

Agenda for an anthropology of pharmaceutical practice.

Over the last two decades, patterns of pharmaceutical-related behavior and the cultural interpretation of medicines have been examined by anthropologists in several cultural settings. In this paper the authors identify additional issues warranting study so as to broaden the scope of pharmaceutical anthropology, utilizing as a unifying focus the examination of pharmaceutical use in the context of social transformation. Ten interactive themes are presented which bridge micro-level and macro-level investigations of pharmaceutical use. The discussion moves from the discourse on 'rational drug use' to the rationales which underscore drug prescription, manufacture, and demand.

Illness semantics and international health: the weak lungs/TB complex in the Philippines.

Attention is drawn to illness semantics and the need to move beyond health social science research on discrete diseases to sets of illnesses perceived to be interrelated within popular health culture. Considered is the weak lungs/TB complex as it is conceptualized in relation to other types of lung disease as well as predisposing factors which influence the moral identity of the afflicted and the social relations of illness. The illness category weak lungs is broad and covers a variety of symptom states inclusive of TB. While some people equate weak lungs with TB, many others think of weak lungs as a condition which may develop into TB over time. TB is recognized to be contagious, but many people do not perceive weak lungs to be contagious. Treatment practice is discussed in relation to perceptions of illness severity, economics, expectations from medicines and coexisting health concerns. Faith in biomedicine is strong. Broad usage of the term weak lungs affects self-treatment practices and over-the-counter purchase of TB medications. Several TB medicines are labeled in such a way as to give the impression that they are vitamins for the lungs. This association leads people to think that the medication is useful for all illnesses which weaken the lungs, even if taken for a short duration. Attention is drawn to the manner in which inappropriate use of TB medication increases the chances of drug resistance. Data presented on TB drug resistance in the Philippines suggests why a consideration of illness semantics is important.

Limitation of medical care: an ethnographic analysis.

This ethnographic study has shown how one attempt to apply ethical principles through a routine procedure failed to fit the clinical context and, in the two cases studied, served to counteract the very foundation these principles were based on--that patients or their families have the right to determine life-and-death decisions regarding code status. The results suggest that the use of well-meaning forms that are intended to facilitate decision making can, in the absence of appropriate guidelines, routinize the doctor-patient discourse to meet bureaucratic needs, narrowing rather than expanding understanding and communication. Bioethical principles implemented in abstraction, apart from the complex intricacies of the doctor-patient-family relationship and the sociocultural influences upon which this relationship is dependent, may be counter-productive to patient interests. As bioethicists and clinicians work to implement the demands of the Patient Self-Determination Act, they will undoubtedly try to forestall legal problems, assure ethical consistency, facilitate auditing, and promote documentation by creating forms. They may look to create inventories, such as the Limitation of Medical Care form described here, or turn to other, less explicit, means of documentation. This study suggests that, in these efforts, genuine attention should be given to patient concerns, not just to the ethical or institutional needs of medicine. This shift in focus from outcome to process can enhance patient and clinician satisfaction, help resolve difficulties in reaching consensus between involved decision makers, and return the power in DNR decision making to patients and families.

Do-not-resuscitate discussions: a qualitative analysis.

The literature to date on Do-Not-Resuscitate (DNR) decision-making is based upon data derived from structured questionnaires, hypothetical scenarios, descriptive epidemiology, or simulated discussions. Lacking in the literature has been a critical examination of the health care professional-patient-family relationship and its impact on decision-making regarding resuscitation. The purpose of this study is to identify and describe organizational and communication factors that affect the process and outcome of DNR discussions and decision-making. Individual and focus-group interviews were conducted with sixteen key informants professionally knowledgeable about resuscitative issues. Thematic analysis of these interviews revealed that a variety of cultural and professional values, as well as previous personal experiences, influenced the assumptions that providers made when engaging in DNR decision-making. Specific recommendations are made to help family physicians identify communication strategies that foster understanding and lead to participatory decisions about resuscitation among patients and families.
