Family planning KAP survey in Gaza.

This study explores the reproductive attitudes, contraceptive use, demand for family planning and related topics of a representative sample of the female population of reproductive age resident in a Refugee Camp in the Gaza Strip. A cluster sample of 841 resident women of reproductive age (15-49 years) was interviewed in their homes. Univariate and multivariate statistical analyses were performed using BMDP software. 98% of the interviewees favour family planning and 88% plan to use a contraceptive in the future. However, 52% of the women at risk do not use any contraception because of their husband's opposition, fear of side effects or lack of knowledge. The risk of having seven or more children is positively associated with a woman's low educational level and husband's desire for more than seven children. Despite favourable attitudes regarding family planning, there is ignorance and the prevalence of contraception use is low. There is a gap between fertility preference and achievement.

Sex education in secondary schools: an Italian experience.

PURPOSE: To evaluate the impact on Italian teenagers' knowledge and attitudes of an experimental program in sex education. METHODS: The program consisted of five workshops in five public secondary schools in Rome. The impact of the program was evaluated with three questionnaires designed for this study. A pretest evaluated baseline knowledge, a posttest measured the gain in knowledge, and a third questionnaire estimated retention of information 4-6 months later. Three hundred seventy-six students attending secondary school participated in the program. Thirteen questions were selected for the analysis, and improvement was measured by the difference between pretest and posttest scores. RESULTS: Ninety-six percent of the sample was in favor of sex education programs in schools. The students had an average 50% gain in the percentage of correct answers following the course. The mean score based on the number of correct answers to questions showed a baseline value of 5.00, a posttest value of 11.80, and a test value 4-6 months later of 10.7. Results showed students' positive attitude toward school sex education courses, low baseline knowledge, and a good ability to learn. CONCLUSIONS: In Italy there is a need for collaboration between schools and local health services to promote knowledge and prevention in reproductive health among teenagers.

High frequency of antithyroid autoantibodies in pregnant women at increased risk of gestational diabetes mellitus.

BACKGROUND: Thyroid autoantibodies (ThyAb) and subclinical hypothyroidism occur more frequently in pregnant women with insulin-dependent diabetes mellitus than in healthy pregnant women. Few studies have investigated the presence of ThyAb in women with gestational diabetes mellitus (GDM), and no significant association between diabetes in pregnancy and thyroid function has been reported. OBJECTIVE: To assess the thyroid biochemical profile and estimate the prevalence of ThyAb in a group of pregnant women at increased risk of GDM due to family and personal risk factors, and to investigate the relationship between a positive family history of diabetes or thyroid diseases and the eventual presence of ThyAb during pregnancy. METHODS: Oral glucose tolerance, serum ThyAb and thyroid function were evaluated in 181 pregnant women with increased risk for GDM (study group). Seventeen healthy pregnant women without risk factors for GDM and with a normal glucose tolerance were recruited as controls. RESULTS: The women who developed GDM showed a mean free thyroxine concentration significantly lower than that observed in the healthy pregnant women and in those with impaired gestational glucose tolerance and normal glucose tolerance. Twenty-nine of the 181 women in the study group (16%) were ThyAb positive. However, the risk of being ThyAb positive during pregnancy was three times greater in the women with positive family history of both diabetes mellitus and thyroid disease than in those with no family history of these conditions. CONCLUSIONS: This study showed that women with increased risk of GDM, mostly those with family history of diabetes mellitus and thyroid disease, also have an increased risk of being ThyAb positive during pregnancy. It also highlighted the importance of evaluating thyroid function in pregnant women with impaired glucose tolerance, in view of their increased risk of subclinical hypothyroidism.

[Congenital forms of hypothyroidism: study of risk factors and preventive interventions].

Maternal and child health represents one of the most relevant fields of interest in public health and particular attention is given to congenital pathologies. In Italy, the incidence of congenital hypothyroidism (CH) is 1:3200 live birth. CH is diagnosed at birth by neonatal thyroid screening. This allows a precocious onset of substitutive therapy which avoids severe psychomotor deficits in infants with CH. Moreover, the newborn screening program have permitted to identify transient disorders of thyroid function in newborns. These are essentially due to neonatal, maternal and environmental risk factors, especially iodine deficiency. The National Register (NR) of infants with CH was established in 1987. The aim of the NR is to provide disease surveillance and to monitor efficiency and effectiveness of neonatal screening. Furthermore, the NR represents an useful tool for developing epidemiological studies to identify possible environmental and/or familial risk factors of CH.

[Incidence of measles in Italy in the 1985-1994 period].

Measles notifications in Italy underestimate the actual incidence by a factor of ten, as it is ascertained by seroepidemiological investigation. In the decade 1980-89, 45,000 measles cases were notified, on average, per year. Since 1988 mass vaccination campaigns were implemented in several Italian regions. The strategy aimed to offer the prophylaxis actively to all children aged 13 months to 8-12 year for whom a sure recollection of measles was absent. The study has aimed to evaluate the impact of the strategy that worked in the period 1989-91, on the standardised average annual incidence of measles notification, comparing the periods 1985-89 and 1990-94. A reduction of 45% resulted all over Italy. On the contrary the incidence of chickenpox notifications has increased, indicating that the notification system did not worse.

[Pilot study on compulsory vaccination coverage].

The disappearance of diphtheria and poliomyelitis is the best evidence of the efficacy of the vaccination strategies adopted in Italy. The active offer of the prophylaxis, reinforced by law, has characterised the operational aspects of the strategy. The active surveillance system is the main tool to take under control the effectiveness of health services responsible for vaccination. This system could be more easily implemented if the health services will be given a specific software aiming to handle and evaluate vaccination registers. The present pilot study, performed in the regions Marche and Sardegna, is an example of active surveillance and it is based on the ARVA software produced by the Istituto Superiore di Sanità. The results show a good level of coverage (> 95%) within the second year of life. Unsatisfactory results were obtained on the timing of vaccinations, as recommended by the vaccination schedule, mostly for the third doses.

Seroepidemiological evaluation of 1989-91 mass vaccination campaigns against measles, in Italy.

In 1989-91 anti-measles vaccination campaigns were conducted in several Italian regions to vaccinate all children aged between 13 months and 10-12 years without a history of measles or measles vaccination. This study was conducted to evaluate serological status after the mass vaccination campaigns. In 1994, capillary blood samples were collected from randomly selected children, aged 2-14 years, living in 13 local health units. Antibody titres were determined by ELISA. Blood spot samples were analysed for 4114 (75.6%) of 5440 selected children. Among the 835 that reported measles before 1990, 806 (96.5%) were immune and of the 2798 vaccinated, 2665 (95.2%) were immune. The Edmoston-Zagreb (E-Z) strain vaccine was associated with a lower level of immunity than the Schwarz (SW) strain. A history of measles identified almost all immune children. Vaccination with the SW strain conferred persistent immunity (at least 5 years) in 98% of vaccinees. The strategy was able to unite natural and induced immunity.

[Transient congenital hypothyroidism in iodine deficiency areas. Gruppo di Studio per il Registro Nazionale degli Ipotiroidei Congeniti].

On the basis of data collected in the National Register of infants with congenital hypothyroidism (CH), a mean incidence of 1 case of CH to 3200 live births has been estimated in Italy. Nevertheless a higher incidence (> 1:2000) than national mean value has been observed in several districts of our country. The aim of this study was to verify a possible occurrence of transient hypothyroidism (TH) in these areas. Results of our study showed that the proportion of infants with thyroid in situ was significantly higher in the areas with very high CH incidence than in the remaining parts of the country. Also serum TSH levels at confirmation showed a less severe hypothyroidism in infants of these areas when compared with the other CH infants. Furthermore, preliminary results of diagnosis reevaluation showed 58% of TH in the areas with CH incidence > 1:2000. Lower percentages of TH have been observed in the other areas in relation to the decreasing of CH incidence. Most of the high CH incidence areas are historically affected by iodine deficiency. This observation supports the hypothesis that iodine deficiency can contribute to the occurrence of transient disorders of thyroid function in our population and stresses the need of promoting diffusion of an adequate iodine prophylaxis.

Comparative clinical evaluation of the effect on carbohydrate and lipid metabolism of two norethisterone-containing hormonal contraceptives: Mesigyna and TriNovum.

The effect on carbohydrate and lipid metabolism of two hormonal contraceptive preparations containing norethisterone (commercially known as Mesigyna and TriNovum) was studied in a total of 60 women, before and after 6 months of treatment. Carbohydrate metabolism was evaluated by means of a euglycemic glucose clamp test; lipid metabolism was monitored by measuring total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, and triglycerides. The two groups were properly matched with the exception of pretreatment levels of cholesterol and LDL-cholesterol. At the end of treatment, no difference was found within or between groups in fasting glucose and insulin levels and in glucose rate of disappearance. A significant increase in total cholesterol, HDL-cholesterol, and VLDL-cholesterol was found in both groups at the end of the treatment period; in addition, TriNovum caused a significant increase also in triglycerides. In conclusion, the safety of both preparations with regard to carbohydrate metabolism was confirmed using the most accurate method available; furthermore, changes in lipid metabolism were such as to have little clinical significance.

Thyroid autoimmunity in pregnant women at risk for GDM.

Presence of antithyroid autoantibodies (ThyAb) during pregnancy is strictly related to the risk of developing post partum thyroiditis (PPT) and this risk is increased in IDDM pregnant women. Gestational diabetes mellitus (GDM) is defined as carbohydrate intolerance of variable severity that begins, or is first diagnosed, during pregnancy. GDM is considered a risk factor for both type 1 and type 2 diabetes and various non-organ specific autoantibodies have been found to be associated with GDM, although there is little information on the association of GDM with thyroid autoimmunity. In this study oral glucose tolerance and prevalence of ThyAb were evaluated in a group of 41 pregnant women at increased risk of developing GDM and in a healthy control group. Our results showed that 22% of GDM risk group had impaired glucose gestational tolerance (IGGT) or GDM at the time of oral glucose tolerance test (OGTT). Moreover, ThyAb prevalence found in the women at increased risk of GDM (14.6%) was similar to that observed in healthy pregnant controls (12.5%). Nevertheless ThyAb frequency was higher in those GDM risk women with family history of diabetes (30.7%).

Reducing pain of first trimester abortion under local anaesthesia.

The study aimed to estimate the pain related to first trimester abortion under local and general anaesthesia. One hundred and eighty-one women undergoing abortion of first trimester under local anaesthesia and 198 under general anaesthesia were interviewed 1 h after the end of the procedure. About 50% of all women described their experience as less painful than expected. Over 50% of the women described the pain during the procedure as mild or moderate according to the verbal rating scale. The step-up logistic regression analyses identified four important variables: time interval less than 2 min from local anaesthesia injection to the beginning of the procedure (RR = 3), lack of choice between local and general anaesthesia (RR = 1.9), history of frequent use of analgesics (RR = 1.9) and nulliparity (RR = 1.7). These data indicate that skillfully performed abortion with local anaesthesia is a procedure tolerated by most women. Moreover, because it carries lower risk of complications and costs less, its use should be encouraged.

Persistence of immunity to poliomyelitis among a southern population that received four doses of OPV 5 to over 15 years before.

The immune status against polioviruses was investigated in a population of 545 students aged 11-20 years residing in the Neapolitan area, who had completed the vaccination cycle with four doses of OPV 5 to over 15 years before. Assuming as unprotected those individuals without detectable neutralizing antibodies at the dilution 1:2, nobody resulted without protection against all types of poliovirus; 0.7% lacked antibodies only against type 1, 0.6% only against type 3 and none against type 2. A very slight decreasing trend was observed for GMT values in function of the distance from the last dose of OPV for polio 1 and 2, but not for polio 3. As expected, GMT values for polio 2 resulted higher than those for polio 1 and both were higher than those for polio 3, when calculated by age groups as well as by distance groups. The last four Italian cases of autochthonous paralytic poliomyelitis, occurred in the period 1981/83, regarded unvaccinated children aged 6 months-2 years, residing in the same geographical area to which the study population belong. In the same area a delay of immunization practices was also ascertained in the recent past. Results of this study confirm that a priority for public health services is to devote their human and economic resources to reduce the vaccination delay more than administrate a further fifth dose of OPV at the age of twelve.

Comparison of capillary blood versus venous blood samples in the assessment of immunity to measles.

Seroepidemiological investigations are essential for assessing the efficacy of measles vaccination programmes. However, when large-scale sampling is needed, a major difficulty is the problem of taking venous blood, especially in children. An alternative method is the collection of capillary blood samples spotted on filter papers. The eluted extract from these 'blood' spots can be used instead of serum samples for measles laboratory diagnosis or investigations. Measles antibody detection is readily carried out by ELISA on serum samples. The same technique can be used on eluates from capillary blood spots. Measles antibody titres determined on matched serum and blood spot samples from 27 children were compared. A strong correlation was found between the results obtained with the two methods of blood sampling.

Risk factors for the co-occurrence of partial epilepsy, cerebral palsy and mental retardation.

A case-control study (64 cases and 209 controls) was carried out to identify risk factors for the co-occurrence of early-onset partial epilepsy, cerebral palsy and mental retardation in children with and without cerebral malformations. History of epilepsy in first-degree relatives, maternal diseases in the two years before pregnancy, placental pathologies, low gestational age, being small for dates, neonatal convulsions and the need for cardiopulmonary resuscitation were associated with partial epilepsy, cerebral palsy and mental retardation. A family history of epilepsy in first-degree relatives was surprisingly frequent in both groups, suggesting that genetic factors play an important role for children with and without cerebral malformations.

[Neonatal screening in congenital hypothyroidism in Italy. The National Registry].

Neonatal screening for congenital hypothyroidism (CH) began in Italy in 1977 and then progressively developed covering 97% of live births in 1992. The National Register of infants with congenital hypothyroidism was established in 1987 as a project of the Health Ministry and is coordinated by the Italian Institute of Health. The aim of the Register is to provide disease surveillance, to monitor the efficiency and effectiveness of neonatal screening and to allow the identification of possible etiological risk factors in congenital hypothyroidism. The results of the Register provided valuable epidemiological informations about congenital hypothyroidism in Italy and evidenced several areas in whom an increased incidence probably caused by iodine deficiency was observed. Discussion of Register data during annual national meetings has allowed an improvement of the screening program with particular regard to the beginning of therapy with L-thyroxine and its dose. Because of the wide spectrum of collected information, the National Register represents a useful tool for developing of collaborative studies concerning some aspects of CH not yet completely elucidated.

[The evaluation of the risk factors for congenital hypothyroidism: the outlook of a case-control study].

The availability of a National Register of congenital hypothyroid infants allowed to perform descriptive studies on characteristics of the cases and the efficiency of the neonatal screening. Continuous and exhaustive recording of data concerning congenital hypothyroidism cases provided valuable epidemiological informations about congenital hypothyroidism in Italy. Moreover, the National Register allowed to develop a network of collaboration which can promote a population based case-control study. As the etiopathogenesis of congenital hypothyroidism has not been completely elucidated, performing of a case-control study can contribute to evidence the most important risk factors of congenital hypothyroidism and to improve the prevention also by prenatal diagnosis of this disease. Screening centers will be involved in the study and questionnaires of the National Register for congenital hypothyroidism will be used to record case and control informations. A biological bank concerning cases, controls and their parents, will be organized.

Family planning in Italy.

In the past 5 years, four knowledge, attitude and practice (KAP) surveys on family planning have been organized by the Unit of Population Survey Methodology of the Istituto Superiore di Sanita' (National Institute of Health). These surveys show that during the past 20 years, use of reliable contraceptives in Italy has increased, particularly in the North, encouraged by the more open attitude toward sexual behavior, following legalization of the provision of information on contraception and abortion upon request, and other social and cultural changes. In 1989 and 1991, 25% of women in Central and Southern Italy were using the pill or an IUD. However, the percentage of women not using contraceptives was still high (26% in 1989, and 19% in 1991) and withdrawal was the most widely used method (31% and 33%). The data show large regional differences. The main reasons for not using contraception, in the 1989 study, were fear of side-effects and ignorance, especially in the youngest and oldest women. Those least likely to use modern contraception were the young, the ill-educated and the nulliparous women. Lack of information seems to be the main problem in Italy. In fact, the 5044 women interviewed showed a medium level of knowledge of contraception, with only 63% who could identify correctly the fecund period in the menstrual cycle. However, their attitude toward the use of modern contraception was positive; 65% of the women interviewed said they would recommend the Pill or an IUD to a friend, and 10% of them would recommend condoms.(ABSTRACT TRUNCATED AT 250 WORDS)
