Contraceptive use among women admitted with abortion in Nairobi.

In this study, a total of 519 patients were interviewed. 82.5% had incomplete abortion. The implication of abortion especially when induced is emphasised. Economic implications that are contributed by the youth are stressed. 83.6% of the patients had not used any contraception. The role of contraception in preventing unwanted pregnancy and therefore induced abortion is stressed. The role of the physician in providing contraception and appropriate contraceptive knowledge is discussed.

Awareness and acceptance of hepatitis B vaccination in Clementi, Singapore.

Hepatitis B Virus infection, a public health problem in Singapore, can be effectively controlled by vaccination. This paper reports on a study conducted in 1988/89 to ascertain the awareness and uptake rate of Hepatitis B vaccination. A list of children born between November 1986 and May 1987 in the catchmen zone of the Clementi Maternal and Child Health (MCH) Clinic was obtained. Out of a total of 257 children, 226 (87.9%) responded to our study in May 1988 which was part of a larger community health survey carried out by a group of medical students. The vaccination uptake rate was 23%. The awareness of the parents on Hepatitis B virus infection and vaccination was assessed using a standardised questionnaire. About two-thirds were aware of the main modes of Hepatitis B transmission, 46.5% were aware of the long-term consequences of Hepatitis B infection and 6.6% thought that the vaccine was not safe from serious side effects. A follow-up survey of the respondents was carried out in August 1989. The Hepatitis B vaccination uptake had increased to 48.3%. The immunisation status showed a correlation with the ethnic group, father's occupation and awareness score of respondents. The more than two-fold increase in uptake rate can be attributed to a reduction in the cost of Hepatitis B vaccination and a vigorous nation-wide education programme during the preceding year.

[The molecular function of oncogenes].

Cancer represents a disruption of the processes in normal cells. To understand cancer, and thereby develop effective treatment, it is necessary to learn about normal reactions in the cells, and their connections. Thus cancer research has been an important source of knowledge about normal cells. Oncogenes are genes that transform normal cells into cancer cells. More than 60 oncogenes have been discovered, and many malignant diseases have been linked to these genes. Human cells contain a normal version of oncogenes, known as protooncogenes, which participate in the normal, cellular processes. This discovery has been of major importance for our understanding of cancer and molecular genetics.

Social support and outcome in teenage pregnancy.

This paper presents information on the role and significance of social support for the occurrence of health and birth problems among adolescent mothers and their babies. Pregnant teenagers (N = 268) were interviewed during the course of pregnancy and again approximately four weeks after delivery, and hospital records were abstracted. The significance of family support, friend support, and partner support, assessed during the pregnancy, were examined in relation to infant and mother outcomes assessed at or after the birth. Infant outcome was indexed by birth weight, with gestational age controlled; mother outcome in terms of psychological adaptation was indexed by depressive symptomatology among adolescent mothers. Socioeconomic background was found to influence relationships between social support and both infant and mother outcomes.

Helping teenagers postpone sexual involvement.

In 1983, the Henry W. Grady Memorial Hospital in Atlanta began a family planning-based outreach program for eighth graders in a local school system. The program is led by older teenagers and focuses on helping students resist peer and social pressures to initiate sexual activity. Evaluation of the program, based on telephone interviews with 536 students from the hospital's low-income population, revealed that among students who had not had sexual intercourse, those who participated in the program were significantly more likely to continue to postpone sexual activity through the end of the ninth grade than were similar students who did not participate in the program. Because of their lower rate of sexual activity, program students also experienced comparatively fewer pregnancies than no-program students.

Sexual decision making in young black adolescent females.

Participant observation and a questionnaire guide were used to conduct in-depth interviews with five 14-year-old, black, pregnant or recently delivered girls to obtain a broad and detailed view of perceptions and interpretations of the factors that led to the initiation of sexual activity and the decision to maintain the pregnancy that resulted. Four key and several supporting factors that influenced the girls' sexual decisions emerged from the data. The key factors centered around the girls' attempt to establish a relationship based on trust, a belief in their lack of vulnerability to become pregnant, family structure, and their beliefs about the alternatives available once a pregnancy was confirmed. Some of the findings were consistent with those reported in the literature, while others were not. Further research is needed on the father of the infant as well as the mother of the adolescent girl to assess their perceptions of the factors they believe influence teenagers' sexual decisions.

Women's use of mammographic screening: the role of information, cues, and reinforcement.

Questionnaires were distributed to 359 women who had mammograms during the previous six months. Data were obtained on: 1) demographic variables; 2) perception of risk and sources of knowledge about breast cancer and mammography; 3) cues or events which initiated action to obtain a mammogram; and 4) behaviors or events which may reinforce the use of the procedure. A major goal of the research was to obtain information on factors hypothesized to effect women's use of mammography for the detection of breast cancer. High education and income levels, characteristic of women using screening procedures, were found in this sample. Availability of information and a realistic perception of risk were not sufficient motivators to obtain a mammogram. The recommendation of a health professional was reported to be the single most important motivating factor by 71% of the sample. Following the procedure, relief of anxiety, and verbal reinforcement by health professionals, friends, or relatives were reported. These results suggest that the most important cue for many women to obtain a mammogram is recommendation of a health professional. The role of reinforcement in repeating the behavior requires further clarification.

Adoption vs. parenting decisions among pregnant adolescents.

The choice of adoption is rare among pregnant adolescents. This exploratory study used regression analyses to ascertain which demographic, social, and intervention variables were related to this decision. The adolescents with mothers who favored adoption and/or had few parenting peer models were more likely to choose adoption. Age, knowledge of peers who had chosen adoption, grades in school, level of involvement in a comprehensive adolescent pregnancy program, and participation in individual therapy or Decision-Making Group were not significantly related to the decision. Decision-Making Group is a once-a-week therapy session that focuses on adoption vs. parenting decisions for pregnant adolescents. Eighty-seven percent of the adolescents who participated in these sessions found them helpful. The policy implications for adolescent pregnancy programs are explored.

Oral rehydration therapy in a rural area, northern Thailand.

A cross-sectional sampling survey of mothers' practice of ORT in Amphoe Bunpotphesai in the northern part of Thailand included 1,619 children under five. Two hundred and six children were reported to have 223 diarrheal episodes. The incidence of diarrhea in children under five was 3.4 episodes per child per year. When children had diarrhea 65.5 per cent of mothers sought help from health providers, 25.2 per cent treated their children with drugs bought from stores, 2.3 per cent used herbal medicine and 6.1 per cent did not treat their children. 50.7 per cent of diarrheal episodes mother gave ORT, using ORS 19.7, commercial electrolytes mixture 16.6 and home available fluid 14.4 per cent. The accuracy of dilution of electrolytes powder from the packets was checked in 80 incidences. 31.8 and 27.8 per cent of mothers made correct dilution of ORS and commercial electrolytes products respectively. Health providers carried both ORS and commercial electrolytes packets. ORS added to a glass of water was found in 13.6 per cent which was 3 times concentrated. Commercial electrolytes products were too dilute in 72.2 per cent. 17.5 per cent of mothers divided electrolytes powder to add in one spoon of water to treat their children as one drug dose. Data showed that the ORT use rate was 50.7 per cent. Home available fluid was used by 14.4 per cent. ORT should be further promoted to control diarrheal diseases and health providers should give instructions to every mother or child minder on how to dispense ORS or electrolytes packets for appropriate dilution and use.

Family environment, affect, ambivalence and decisions about unplanned adolescent pregnancy.

This study investigated the relationships among family environment, demographic measures, the decisions made by unintentionally pregnant adolescents regarding postdelivery plans and the certainty with which these decisions were made. Subjects were 175 pregnant adolescents, ages 14 through 22, who intended to carry their pregnancies to term. Greater uncertainty was associated with living with both natural parents or with mother only. Higher levels of negative affect were related to lower levels of perceived family cohesion, independence, expressiveness, and intellectual-cultural orientation. Age, trimester of pregnancy, and family constellation also were related to levels of negative affect. Discriminant analysis revealed that subjects choosing adoption were more likely to be older and to be white than were those choosing to keep the child. They also tended to perceive higher levels of expressiveness and independence in their families. The implications of these findings for the delivery of services and for future research efforts in this area are discussed.

Knowledge of schoolchildren about the acquired immune deficiency syndrome.

Teenage schoolchildren are often sexually active and first experiments with drugs can occur at this age. A questionnaire survey of the knowledge and source of information about the acquired immune deficiency syndrome was carried out on 232 15-year-olds at a school in Fife. The results showed that this younger age group is well-informed about AIDS, particularly methods of transmission of the virus, and that the majority of information was obtained from television (95%) and leaflets (85%).

Parents' behavioral norms as predictors of adolescent sexual activity and contraceptive use.

The influence of parental factors on adolescent sexual behavior and contraceptive use has been examined previously, and findings have been contradictory. Previous studies, which found little relationship between parental norms and adolescent sexual activity, have been limited by their failure to recognize developmental differences in the relative weight of parent and peer influences between younger and older teens and by use of selected samples, resulting in a restriction of range. The current study differs in that it utilizes a clustered sample household survey of 329 males and females, aged 14 to 17, and 470 of their parents. Using multiple regression analysis, it was found that parents' reported behavioral norms account for 5% of the variance in whether adolescents have had intercourse, and for 33% of the variance in use of contraception at last intercourse. The study suggests that while parents' normative beliefs have limited effect in the decision to become sexually active, they have considerable impact on later contraceptive use.
