OBJECTIVES: This report presents 1997 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal demographic characteristics including age, live-birth order, race, Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco and alcohol use); medical care utilization by pregnant women (prenatal care, obstetric procedures, complications of labor and/or delivery, attendant at birth, and method of delivery); and infant health characteristics (period of gestation, birthweight, Apgar score, abnormal conditions, congenital anomalies, and multiple births). Also presented are birth and fertility rates by age, live-birth order, race, Hispanic origin, and marital status. Selected data by mother's State of residence are shown including teenage birth rates and total fertility rates, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS: Descriptive tabulations of data reported on the birth certificates of the 3.9 million births that occurred in 1997 are presented. RESULTS: Birth and fertility rates declined very slightly in 1997. Birth rates for teenagers fell 3 to 5 percent. Rates for women in their twenties changed very little, whereas rates for women in their thirties rose 2 percent. The number of births and the birth rate for unmarried women each declined slightly in 1997 while the percent of births that were to unmarried women was unchanged. Smoking by pregnant women overall dropped again in 1997, but continued to increase among teenagers. Improvements in prenatal care utilization continued. The cesarean delivery rate increased slightly after declining for 7 consecutive years. The proportion of multiple birth continued to rise; higher order multiple births (e.g., triplets, quadruplets) rose by 14 percent in 1997, following a 20 percent rise from 1995 to 1996. Key measures of birth outcome--the percents of low birthweight and preterm births--increased, with particularly large increases in the preterm rate. These changes are in large part the result of increases in multiple births. (+info)
A prospective multicentre study in Sweden and Norway of mental distress and psychiatric morbidity in head and neck cancer patients.
(10/1240)
A Swedish/Norwegian head and neck cancer study was designed to assess prospectively the levels of mental distress and psychiatric morbidity in a heterogeneous sample of newly diagnosed head and neck cancer patients. A total of 357 patients were included. The mean age was 63 years, and 72% were males. The patients were asked to answer the HAD scale (the Hospital Anxiety and Depression scale) six times during 1 year. The number of possible or probable cases of anxiety or depression disorder was calculated according to standardized cut-offs. Approximately one-third of the patients scored as a possible or probable case of a major mood disorder at each measurement point during the study year. There were new cases of anxiety or depression at each time point. The anxiety level was highest at diagnosis, while depression was most common during treatment. Females were more anxious than males at diagnosis, and patients under 65 years of age scored higher than those over 65. Patients with lower performance status and more advanced disease reported higher levels of mental distress and more often scored as a probable or possible cases of psychiatric disorder. Our psychometric analyses supported the two-dimensional structure and stability of the HAD scale. The HAD scale seems to be the method of choice for getting valid information about the probability of mood disorder in head and neck cancer populations. The prevalence of psychiatric morbidity found in this study emphasizes the importance of improved diagnosis and treatment. (+info)
Maternal predictors of perinatal mortality: the role of birthweight.
(11/1240)
BACKGROUND: Many maternal characteristics increase the risk for perinatal death. To locate potential sites for intervention, it is important to identify these risk factors and examine how much of the excess mortality is explained by infants' low birthweight. METHODS: Data on all newborns in Finland born between 1991 and 1993 (N = 199,291, of which 1461 were perinatal deaths) were obtained from the Medical Birth Register. Logistic regression analysis was used to adjust for background variables, both including and excluding infants' birthweight. The percentage reduction in odds ratios after adjustment for infants' birthweight was used to estimate the contribution of infants' low birthweight to the excess mortality. RESULTS: After adjusting confounding factors, increased risk for perinatal death was found for eight maternal characteristics. In the following the increased risk is given as odds ratios and the proportions of the excess mortality explained by infants' low birthweight are in parentheses: in-vitro fertilization 4.12 (> 100%); earlier stillbirth 3.43 (87%); higher maternal age, from 1.21 to 3.08 (38-99%); maternal diabetes 2.87 (50%); lower socioeconomic status, from 1.30 to 1.70 (27-44%); smoking during pregnancy 1.45 (> 100%); single mother 1.44 (50%); first birth 1.36 (75%). CONCLUSIONS: Excess mortality due to maternal risk factors occurred mainly through their tendency to cause low birthweight. However, the excess mortality associated with low socioeconomic status, single motherhood, and diabetes was mediated by other mechanisms in addition to low birthweight. (+info)
Age and gender variation in the impact of household structure on elderly mortality.
(12/1240)
BACKGROUND: There is little information about the impact of household structure and composition on elderly mortality in developing countries. This study examines the impact of relationship to head of household, and the presence of co-resident spouses and sons on elderly mortality in rural Bangladesh with a particular focus on age and gender differences. METHODS: A total of 9365 individuals aged > or = 60 at baseline (5128 males and 4237 females) in the Matlab Surveillance area in rural Bangladesh were followed for a period of 8 years (1974-1982) with all predictors (the presence of a spouse, one or more co-resident adult sons, relationship to head of household, household economic status, age and disability status) being measured at the beginning of follow-up. Cox proportional hazard models were used in the analysis. RESULTS: Being the head of household had a significant impact on reducing elderly mortality for both men and women. The presence of a spouse reduced mortality for all elderly men but had a significant beneficial impact only on women whose husbands were heads of households. Finally the presence of one or more co-resident adult sons reduced mortality for elderly women but not for elderly men. For all three of the above predictors there was a decline in effect with the age of the elderly. CONCLUSIONS: Relationship to head of household and the presence of spouses and sons have powerful impacts on reducing mortality for elderly men and women in rural Bangladesh with the effects varying significantly by gender and age. Furthermore, individual rather than joint access to material resources is an important determinant of elderly mortality. (+info)
Determinants of folic acid knowledge and use among antenatal women.
(13/1240)
BACKGROUND: Although recommendations on folic acid use were issued by health authorities in a number of countries in the early 1990s, uptake of peri-conceptional folic acid is still disappointingly low. Regardless of food fortification policies, folic acid promotion will probably be required in most countries to optimize folate levels among women of child-bearing age. The aim of this study was to examine folic acid knowledge and use, and their determinants among antenatal women in the east of Ireland in 1997. METHODS: Three hundred antenatal women attending their initial booking appointment in three Dublin maternity hospitals were surveyed. An interviewer-administered questionnaire was used with questions on folic acid knowledge and use, and demographic and obstetric questions. A univariate analysis of data was undertaken followed by a multivariate analysis using logistic regression to determine factors predicting knowledge and use of folic acid. RESULTS: Seventy-six per cent of respondents had heard of folic acid, 16 per cent had taken it before pregnancy and 51 per cent during pregnancy. Women who had planned their pregnancy, were married and were relatively affluent were significantly more likely to have heard of folic acid, to know that it could prevent neural tube defects and to have taken it peri-conceptionally. Less affluent women tended to use their general practitioner (GP) more as a source of information and advice than those who were better off. In multivariate analysis, marriage and planned pregnancy were important predictors of folic acid knowledge whereas planned pregnancy advice given before pregnancy and relative affluence were predictive of peri-conceptional use. CONCLUSIONS: Many women know of folic acid but do not take it peri-conceptionally. Women may associate folic acid with pregnancy and less with pre-pregnancy. Greater emphasis on peri-conceptional use should improve folic acid uptake. Focusing on less affluent women for folic acid promotion by GPs and other primary care professionals is also important.

Maternal factors, obstetric history and smoking stage of change.
(14/1240)
BACKGROUND: Maternal smoking is known to be associated with low educational status, low social class and younger age groups. The aim of this study was to determine if maternal smoking and stage of change relating to smoking is associated with other maternal variables such as intention to breastfeed and attend antenatal classes, having a planned pregnancy, previous obstetric history and child health problems. METHOD: A cross-sectional survey was carried out of all women who attended antenatal clinics at the Leicester Royal Infirmary NHS Trust over a two-week period. The data comprised 254 completed questionnaires. Results Intention to breastfeed was more common among non-smokers as shown by smoking status (p < 0.001) and smoking stage of change (p < 0.05). Having a planned pregnancy was more common among non-smokers as determined by smoking status (p < 0.001) and stage of change (p < 0.05). Intention to attend antenatal classes showed no significant relationship with smoking status but the majority of those planning to attend antenatal classes were in the action-maintenance stage (p< 0.05). Previous obstetric complications were not associated with either smoking status or stage of change. Smokers were more likely to have at least one child with asthma (p < 0.05) or respiratory infections (p < 0.001). Having at least one child with asthma or respiratory infections was more common among precontemplators (p < 0.05). CONCLUSION: Smoking stage of change should be assessed in antenatal care so that appropriate information can be offered to pregnant smokers. The development and evaluation of stage-specific smoking cessation materials should offer considerable benefits to maternal and infant health. (+info)
Contraceptive characteristics: the perceptions and priorities of men and women.
(15/1240)
CONTEXT: Despite the fact that choosing a contraceptive method is often a decision made by couples, little is known about how men and women differ in their perceptions of the characteristics of various method types, and in the importance that they attach to those characteristics when choosing a contraceptive method. METHODS: The data analyzed here are subsets from two companion surveys conducted in 1991--1,189 men aged 20-27 who were surveyed in the National Survey of Men and 740 women aged 20-27 who were surveyed in the National Survey of Women. Multivariate ordered logit analysis is used to examine how gender is related to both the importance that individuals assign to seven specific contraceptive characteristics when choosing a method, and to perceptions about the extent to which five common method types possess each of these characteristics. RESULTS: Women rank pregnancy prevention as the single most important contraceptive characteristic when choosing a method, with 90% citing it as "very important." The health risks associated with particular methods and protection from sexually transmitted diseases (STDs) are rated as the second most important characteristics by women (each mentioned as "very important" by 77%). In contrast, men consider STD prevention for themselves and their partner to be just as important as pregnancy protection (each mentioned as "very important" by 84-86%), and they rank STD prevention as more important than other health risks (by 72%). Women, but not men, rank both ease of use and the need to plan ahead as being more important characteristics than a method's interference with sexual pleasure. Both men and women have an accurate understanding of the strengths and weaknesses of particular methods, but differ enough in their perceptions to alter the relative attractiveness of each method. In particular, women have more favorable perceptions than men about the pill, being somewhat more likely than men to believe that the pill is "very good" at preventing pregnancy (75% vs. 67%) and to say that it is very good at not interfering with sexual pleasure (82% vs. 76%). In contrast, women have generally less favorable perceptions than men about other reversible methods, including the condom: Women were less likely than men to consider the condom very good at pregnancy prevention (29% vs. 46%) or at having no need for advance planning (22% vs. 38%). Gender differences in perceptions about the specific characteristics of contraceptive methods often vary by marital status. CONCLUSIONS: Men and women have somewhat different priorities when choosing a contraceptive method. Despite many similarities between women and men in their perceptions about the characteristics of each method type, numerous differences between them may have an important influence on how couples make their method choices.

Alcoholic cirrhosis is a good indication for liver transplantation, even for cases of recidivism.
(16/1240)
BACKGROUND/AIMS: Alcoholic cirrhosis remains a controversial indication for liver transplantation, mainly because of ethical considerations related to the shortage of donor livers. The aim of this study was to review experience to date, focusing on survival rates and complications, and the effect of alcohol relapse on outcome and alterations in marital and socioprofessional status. METHODS: The results for 53 patients transplanted for alcoholic cirrhosis between 1989 and 1994 were compared with those for 48 patients transplanted for non-alcoholic liver disease. The following variables were analysed: survival, rejection, infection, cancer, retransplantation, employment and marital status, alcoholic recurrence. The same variables were compared between alcohol relapsers and non-relapsers. RESULTS: Recovery of employment was the only significantly different variable between alcoholic (30%) and non-alcoholic patients (60%). Two factors influenced survival in the absence of alcohol recidivism: age and abstinence before transplantation. For all other variables, there were no differences between alcoholic and non-alcoholic patients, and, within the alcoholic group, between relapsers and non-relapsers. The recidivism rate was 32%. CONCLUSION: The data indicate that liver transplantation is justified for alcoholic cirrhosis, even in cases of recidivism, which did no affect survival and compliance with the immunosuppressive regimen. These good results should help in educating the general population about alcoholic disease. (+info)
