Smoking cessation advice recorded during pregnancy in United Kingdom primary care

Background: United Kingdom (UK) national guidelines recommend that all pregnant women who smoke should be advised to quit at every available opportunity, and brief cessation advice is an efficient and cost-effective means to increase quit rates. The Quality and Outcomes Framework (QOF) implemented in 2004 requires general practitioners to document their delivery of smoking cessation advice in patient records. However, no specific targets have been set in QOF for the recording of this advice in pregnant women. We used a large electronic primary care database from the UK to quantify the pregnancies in which women who smoked were recorded to have been given smoking cessation advice, and the associated maternal characteristics. Methods: Using The Health Improvement Network database we calculated annual propotions of pregnant smokers between 2000 and 2009 with cessation advice documented in their medical records during pregnancy. Logistic regression was used to assess variation in the recording of cessation advice with maternal characteristics. Results: Among 45,296 pregnancies in women who smoked, recorded cessation advice increased from 7% in 2000 to 37% in 2004 when the QOF was introduced and reduced slightly to 30% in 2009. Pregnant smokers from the youngest age group (15–19) were 21% more likely to have a record of cessation advice compared to pregnant smokers aged 25–29 (OR 1.21, 95% CI 1.10-1.35) and pregnant smokers from the most deprived group were 38% more likely to have a record for cessation advice compared to pregnant smokers from the least deprived group (OR 1.38, 95% CI 1.14-1.68). Pregnant smokers with asthma were twice as likely to have documentation of cessation advice in their primary care records compared to pregnant smokers without asthma (OR 1.97, 95% CI 1.80-2.16). Presence of comorbidities such as diabetes, hypertension and mental illness also increased the likelihood of having smoking cessation advice recorded. No marked variations were observed in the recording of cessation advice with body mass index. Conclusion: Recorded delivery of smoking cessation advice for pregnant smokers in primary care has increased with some fluctuation over the years, especially after the implementation of the QOF, and varies with maternal characteristics

Gravidez na adolescência e baixo peso ao nascer: existe associação? Embarazo en la adolescencia y bajo peso al nacer: ¿existe asociación? Pregnancy in teenagers and low birthweight infant: is there an association?

OBJETIVO: Verificar a associação entre gravidez na adolescência (dez a 19 anos) e baixo peso ao nascer. MÉTODOS: Estudo transversal realizado em maternidade terciária entre junho de 2000 a junho de 2001. Por sorteio aleatório simples, foram selecionadas mães adolescentes e não adolescentes entrevistadas no primeiro dia após o parto. Aplicou-se a análise multivariada por meio de regressão logística das variáveis implicadas com o baixo peso ao nascer. RESULTADOS: Foram selecionadas 539 duplas (mães e seus respectivos recém-nascidos), sendo 331 (61,4%) mulheres com 20 anos ou mais e 208 (38,5%) abaixo de 20 anos. Entre as adolescentes, 50 bebês (24%) tiveram idade gestacional <37 semanas, enquanto entre as mães acima de 20 anos, 52 (15,7%) eram prematuros (OR 1,58; IC95% 1,00-2,51). Entre as adolescentes, ocorreram 52 (25%) recém-nascidos com peso <2500g e, entre as adultas, 56 (16,9%) tinham baixo peso (OR 1,64; IC95% 1,05-2,56). Entre as que realizaram pré-natal adequado, a ocorrência de baixo peso foi de 12,3% e de 22,1% no grupo cuja assistência foi inadequada. Nesta casuística, a associação encontrada na análise univariada entre baixo peso e mãe adolescente não se manteve na análise multivariada. CONCLUSÕES: Baixo peso ao nascer em gestações na adolescência não pode ser atribuído isoladamente à idade materna.<br>OBJETIVO: Verificar la asociación entre embarazo en la adolescencia (10 a 19 años) y bajo peso al nacer. MÉTODOS: Estudio transversal realizado en maternidad terciaria entre junio de 2000 a junio de 2001. Por sorteo aleatorio simple, se seleccionaron madres adolescentes y no adolescentes entrevistadas en el primer día después del parto. Se aplicó el análisis multivariado mediante regresión logística de las variables implicadas con el bajo peso al nacer. RESULTADOS: Se seleccionaron 539 parejas (madres y sus respectivos recién-nacidos), siendo 331 (61,4%) mujeres con 20 años o más y 208 (38,5%) abajo de los 20 años. Entre las adolescentes, 50 bebés (24%) tuvieron edad gestacional <37 semanas, mientras que entre las madres con más de 20 años, 52 (15,7%) eran prematuros (OR 1,58; IC95% 1,00-2,51). Entre las adolescentes, ocurrieron 52 (25%) recién nacidos con peso <2.500g entre las adultas, 56 (16,9%) tenían bajo peso (OR 1,64; IC95% 1,05-2,56). Entre las que realizaron prenatal adecuado, la ocurrencia de bajo peso fue de 12,3% y de 22,1% en el grupo cuya asistencia fue inadecuada. En esa casuística, la asociación encontrada en el análisis bivariado entre bajo peso y madre adolescente no se mantuvo en el análisis multivariado. CONCLUSIONES: Bajo peso al nacer en gestaciones en la adolescencia no puede ser atribuido aisladamente a la edad materna.<br>OBJECTIVE: To study the association between teenage pregnancy (ten to 19 years old) and low birthweight. METHODS: Cross-sectional study carried out at a tertiary center from June 2000 to June 2001. A simple random drawing selected teenagers and adult mothers who were interviewed during the first day after birth. Multivariate analysis using logistic regression of variables related to low birthweight was applied. RESULTS: 539 pairs (mothers and their newborns) were studied - 331 (61.4%) women with 20 years old or more and 208 (38.5%) <20 years old. Among the adolescents, 50 (24%) infants had gestational age <37 weeks, whereas among mothers over 20 years old, 52 (15.7%) were preterm (OR 1.58; 95%CI 1.00-2.51). Among the adolescent and adult women, there were respectively 52 (25%) and 56 (16.9%) newborns <2500g (OR 1.64; 95%CI 1.05-2.56). Among those who had adequate prenatal care, low birth weight was detected in 12.3 and 22.1% of mothers with adequate and inadequate prenatal care, respectively. The association found in the univariate analysis between low birth weight and maternal age was not sustained in the multivariate analysis. CONCLUSIONS: Low birth weight in teenage pregnancies can not be attributed only to maternal age
