[Increased percentages of breastfed infants in Amsterdam]. / Toegenomen percentages borstgevoede zuigelingen in Amsterdam.

OBJECTIVE: To investigate the prevalence of breastfeeding amongst infants in Amsterdam prior to and following an active breastfeeding policy that has been operating in Amsterdam since 1993; investigate the link between ethnic origin and breastfeeding and the reasons mothers give for stopping breastfeeding. DESIGN: Retrospective, descriptive study. METHOD: During the period 1998 to 2000, 1274 mothers in six child health centres in Amsterdam, the Netherlands, were asked about how they had fed their infant, aged 6 to 8 months, from the first week onwards, and their reasons for starting formula feeding. The breastfeeding percentages were compared with a study for the period 1992 to 1993. RESULTS: During the first week of the infant's life, 87% of the mothers gave breastfeeding, and at 25 weeks this figure was 30%. For the period 1998 to 2000, the breastfeeding rate at 15 weeks was higher compared with the period 1992 to 1993, 45.1% as opposed to 36.4%. An increased percentage of breastfed infants were found in each ethnic group studied. More Turkish and Moroccan mothers than Dutch mothers started to breastfeed, and they breastfed for a similar period. Surinam mothers started breastfeeding as often as Dutch mothers, but breastfed for a shorter period. Concern about inadequate milk supply was stated as the most important reason for starting formula feeding (44%). This was also the most important reason stated by each of the ethnic groups, Dutch (139/411; 34%), Surinam (63/129; 49%), Moroccan (70/130; 54%) and Turkish women (42/67; 63%). CONCLUSION: An active breastfeeding policy in Amsterdam that has been operating since 1993 has been accompanied by an increase in the number of breastfed infants. This has also been the case in non-Dutch groups. Health programmes should devote greater attention to mothers' concerns about a shortage of milk.

[High vaccination rates among children of Amsterdam]. / Hoge vaccinatiegraad van Amsterdamse kinderen.

OBJECTIVE: To examine if in Amsterdam there are social or cultural groups of children with a relatively low vaccination coverage for diphtheria, pertussis, tetanus and poliomyelitis (DPTP) and mumps, measles and rubella (MMR). DESIGN: Descriptive cross-sectional study. METHOD: In the Department of Child Health Care of the Municipal Health Service of Amsterdam all 83,217 children aged 2-12 years living in Amsterdam on the 1st of January 2000 were analysed for vaccination and sociodemographic data collected routinely by the Department of Child Health Care. The sociodemographic data concerned sex, year of birth, country of birth of the mother and child, name of the school and postal code of the home address. Schools were grouped by (religious) affiliation on the basis of the Amsterdam school guide 1999/2000. Based on postal codes children were classified by the neighbourhoods in which they were living. Neighbourhoods were grouped by socio-economic status based on data from the Central Bureau for Statistics. RESULTS: The overall vaccination rates of DPTP and MMR were 92.4% and 93.5% respectively. No important variation in vaccination coverage was identified between more and less affluent neighbourhoods. The uptake rate among foreign children was sometimes slightly higher and sometimes slightly lower compared with native children. Especially foreign children born abroad (Surinam, Antilles, Morocco, Turkey) were not fully vaccinated: 70.9% were fully immunized for DPTP, 79.5% for MMR. Children who visited anthroposophical schools were considerably less frequently fully immunized compared with children visiting other schools: for DPTP and MMR 81.0 and 59.9% respectively versus 94.4 en 95.3% for children attending general municipal schools. CONCLUSION: The vaccination coverage was high in children in Amsterdam. Further improvement of the vaccination uptake might be achieved by a more outreaching attitude to children born abroad, and by more intensely informing sceptical parents about the benefits and (supposed) dangers of vaccinations.

[Ethnic origin and care giving styles relevant to cot death]. / Etnische afkomst en voor wiegendood relevante verzorgingsfactoren.

OBJECTIVE: To examine whether ethnic origin is related to care giving styles relevant to sudden infant death. DESIGN: Prospective/retrospective, descriptive. METHOD: In six child health care centres in Amsterdam, the Netherlands, data about sleep position, bedclothes and passive smoking of infants aged 1-5 months were collected by face-to-face interviews of mothers visiting these centres between February 1997 and October 1998. RESULTS: Eligible for the study were 1815 infants, 919 boys and 896 girls, mean age 2 months. In Amsterdam 12.5% of infants were usually or sometimes put to sleep in a prone position, 31.0% usually or now and then in a side position (but not in a prone position) and 56.5% usually in a supine position. Prone sleeping position was more frequent among Surinamese infants and less frequent among Moroccan infants compared with Dutch infants. Overall use of a duvet among infants was 22.7%. Use of duvets was higher among allochtonous infants; after controlling for demographic factors this difference was not significant, however. 6.3% of the infants had slept in the previous night with a pillow. Use of a pillow was much more frequent among allochtonous than among autochtonous infants: 13% versus 1.2%. Maternal daily smoking during pregnancy and daily smoking by mothers or others at home at time of interview was found in 15.1% and 25.8% of the infants respectively. Almost no Moroccan mothers smoked during pregnancy (0.4%), while Turkish mothers smoked as much as Dutch mothers (18.5% and 21.6% respectively). No differences in daily smoking at home were found between Surinamese, Moroccan and Dutch families (circa 26%). However, daily smoking at home was much more frequent in Turkish families (43.8%). CONCLUSION: Health education about a safe sleeping position, about safe bedclothes and about the dangers of passive smoking is still needed. Education programmes to prevent sudden infant death must take into account ethnic differences in care giving styles. Special attention must be paid to the use of a pillow among allochtonous infants.

Mothers' reports of infant crying and soothing in a multicultural population.

OBJECTIVES: To investigate the prevalence of infant crying and maternal soothing techniques in relation to ethnic origin and other sociodemographic variables. DESIGN: A questionnaire survey among mothers of 2-3 month old infants registered at six child health clinics in Amsterdam, the Netherlands. SUBJECTS: A questionnaire on sociodemographic characteristics and crying behaviour was completed for 1826 of 2180 (84%) infants invited with their parents to visit the child health clinics. A questionnaire on soothing techniques was also filled out at home for 1142 (63%) of these infants. RESULTS: Overall prevalences of "crying for three or more hours/24 hour day" "crying a lot", and "difficult to comfort" were 7.6%, 14.0%, and 10.3%, respectively. Problematic infant crying was reported by 20.3% of the mothers. Of these infants, only 14% met all three inclusion criteria. Problematic crying occurred less frequently among girls, second and later born children, Surinamese infants, and breast fed infants. Many mothers used soothing techniques that could affect their infant's health negatively. Shaking, slapping, and putting the baby to sleep in a prone position were more common among non-Dutch (especially Turkish) mothers than among Dutch mothers. Poorly educated mothers slapped their baby more often than highly educated mothers. CONCLUSIONS: Mothers' reports of infant crying and soothing varied sociodemographically. Much harm may be prevented by counselling parents (especially immigrants) on how and how not to respond to infant crying. Health education should start before the child's birth, because certain soothing techniques could be fatal, even when practised for the first time.

[Bedwetting by Dutch, Surinam, Moroccan and Turkish 3-4, 5-6, and 11-12-year-old children]. / Bedplassen bij Nederlandse, Surinaamse, Marokkaanse en Turkse kinderen van 3-4, 5-6 en 11-12 jaar.

OBJECTIVE: To investigate whether ethnic origin is related to the prevalence of bedwetting among children and how parents handle bedwetters. DESIGN: Descriptive study. SETTING: Department of Youth Health Care in Amsterdam, the Netherlands. METHOD: Parents of children who attended a child health centre in 1992/1993 were interviewed using a questionnaire. A total of 1506 children aged 3-4, 2422 aged 5-6 and 2081 aged 11-12 years participated in the study. RESULTS: The prevalences of bedwetting were 24.6%, 15.7% and 5.4% at 3-4, 5-6 and 11-12 years of age respectively. Moroccan and Turkish 3-4-year-olds wet their beds just as often as Dutch children, Surinamese 3-4-year-olds less often. However, Surinamese, Moroccan and Turkish school children wet their beds more often than their Dutch classmates. For Dutch children the prevalence of bedwetting at the age of 5-6 was clearly lower than at the age of 3-4, in contrast with Surinamese, Moroccan and Turkish children. Non-Dutch bedwetters were rewarded less often for a dry night and punished more often for a wet night than Dutch bedwetters, even at the age of 3-4. CONCLUSION: Bedwetting by school children still occurs often, and more often among non-Dutch than among Dutch children. Possibly, differences between Dutch and non-Dutch parents in the ways they deal with bedwetting plays a part. Appropriate information and support of (especially non-Dutch) parents of young children can perhaps reduce the prevalence of bedwetting at later ages.
