Factors associated with smoking in pregnancy

The aim of this cross-sectional study was to identify factors related to smoking during pregnancy. The sample included 267 puerperae hospitalized in the maternity unit of a university hospital in Porto Alegre/RS. The data were collected through a self-applied instrument and statistically analyzed. The majority of the puerperae (51.3%) were between 18 and 25 years old, 55.4% were nonsmokers, 25.5% were smokers, 19.1% had recently ceased smoking (in abstinence). The nonsmokers had more consultations than the smokers and the abstinent smokers (p=0.025). The number of women who had more than one child was higher among smokers than among nonsmokers and abstinent smokers (p=0.002). Women were more likely to stop smoking before pregnancy when they had a partner who was a nonsmoker (p=0.007). Several factors influence smoking and smoking cessation and these are important in prenatal interventions aimed at pregnant women and their partners

Infant sleep hygiene counseling (sleep trial): protocol of a randomized controlled trial

BACKGROUND: Sleep problems in childhood have been found to be associated with memory and learning impairments, irritability, difficulties in mood modulation, attention and behavioral problems, hyperactivity and impulsivity. Short sleep duration has been found to be associated with overweight and obesity in childhood. This paper describes the protocol of a behavioral intervention planned to promote healthier sleep in infants. METHODS: The study is a 1:1 parallel group single-blinded randomized controlled trial enrolling a total of 552 infants at 3 months of age. The main eligibility criterion is maternal report of the infant’s sleep lasting on average less than 15 h per 24 h (daytime and nighttime sleep). Following block randomization, trained fieldworkers conduct home visits of the intervention group mothers and provide standardized advice on general practices that promote infant’s self-regulated sleep. A booklet with the intervention content to aid the mother in implementing the intervention was developed and is given to the mothers in the intervention arm. In the two days following the home visit the intervention mothers receive daily telephone calls for intervention reinforcement and at day 3 the fieldworkers conduct a reinforcement visit to support mothers’ compliance with the intervention. The main outcome assessed is the between group difference in average nighttime self-regulated sleep duration (the maximum amount of time the child stays asleep or awake without awakening the parents), at ages 6, 12 and 24 months, evaluated by means of actigraphy, activity diary records and questionnaires. The secondary outcomes are conditional linear growth between age 3–12 and 12–24 months and neurocognitive development at ages 12 and 24 months. DISCUSSION: The negative impact of inadequate and insufficient sleep on children’s physical and mental health are unquestionable, as well as its impact on cognitive function, academic performance and behavior, all of these being factors to which children in low- and middle-income countries are at higher risk. Behavioral interventions targeting mothers and young children that can be delivered inexpensively and not requiring specialized training can help prevent future issues by reducing the risk to which these children are exposed.

Women who smoke and stop during pregnancy: who are they?

OBJECTIVES: to identify factors involved in not stopping smoking in spite of being pregnant. METHODS: standardized interviews were applied to 486 pregnant women in the pre-natal clinics of four health centers in the city of Rio de Janeiro, Brazil, between April 2003 and February 2004. Every time a smoker was identified, an additional interview, which included the Edinburgh Postnatal Depression Scale, the Fagerströn scale for nicotine dependence, and the Screening Questionnaire for Adult Mental Disorders, was carried out. RESULTS: the prevalence of smoking, in the initial stages of pregnancy was 21.1%. Most smokers presented a low level of nicotine dependence. Thirty-six percent of them stopped smoking by the first trimester of the present pregnancy without any specific medical intervention. Important differences between those who were able to stop and those who were not were alcohol intake and number of previous attempts at abstinence. Women who stopped smoking drank less during gestation. CONCLUSIONS: stopping smoking during pregnancy seems to be linked to a non-specific drive towards the well-being of the fetus. The number of previous attempts at abstinence was positively related to stopping at the beginning of pregnancy. In spite of the prevalence of the problem, there is still inadequate support for smokers in the prenatal services.OBJETIVOS: identificar fatores envolvidos no comportamento de continuar fumando a despeito de estar grávida. MÉTODO: entrevistas padronizadas foram aplicadas a 486 mulheres grávidas nas clínicas de pré-natal de quatro centros de saúde na cidade do Rio de Janeiro, Brasil, no período de abril 2003 a fevereiro 2004. Todas as vezes que uma fumante era identificada, uma entrevista adicional foi aplicada, contendo a Escala de Edinburgh para Depressão, a escala de Fagerstron para dependência de nicotina e o Questionário de Avaliação de Doenças Mentais em adultos. RESULTADOS: a prevalência de tabagismo nos estágios iniciais da gravidez foi de 21,1%. A maioria das tabagistas apresentou baixo nível de dependência de nicotina. Trinta e seis por cento das mulheres avaliadas pararam de fumar no primeiro trimestre da gestação sem qualquer intervenção médica específica. As mesmas beberam menos durante a gestação e haviam tentado parar de fumar mais vezes anteriormente. CONCLUSÕES: os resultados sugerem uma motivação inespecífica para o bem estar do concepto que envolve as duas drogas lícitas. Aquelas que pararam, tentaram mais vezes anteriormente e também diminuíram o consumo de álcool na gestação atual
