“…Prenatal care begins later in rural areas 31 , although this fact is not independently associated with increased LBW. On the other hand, excessive testing during pregnancy can create anxiety and may lead to an increase of unfavorable outcomes such as LBW 32 .…”

Abstract:Low birth weight (LBW) is one of the main predictors of infant mortality. The global incidence of LBW is around 17%, although estimates vary from 19% in the developing countries like Bangladesh to 5-7% in the developed countries. About one third of delivery is low birth weight. LBW is generally associated with situations in which uterine malnutrition is produced due to alterations in placental circulation. There are many known risk factors, the most important of which are socio-economic factors, medical risks before or during gestation and maternal lifestyles. However, although interventions exist to prevent many of these factors before and during pregnancy, the incidence of LBW has not decreased.

“…Thus, pregnant women with access to better prenatal care L.C. Coimbra et al www.bjournal.com.br services have fewer diseases and their babies have better intrauterine growth, lower rates of low birth weight or preterm births, and lower perinatal and infant mortality (1)(2)(3)(4)(5).…”

Data for two birth cohorts from two Brazilian municipalities, Ribeirão Preto in 1994 and São Luís in 1997/1998, were used to identify and compare factors associated with inadequate utilization of prenatal care and to identify factors capable of explaining the differences observed between the two cities. Prenatal care was defined as adequate or inadequate according to the recommendations of the Brazilian Ministry of Health. The chi-square test and Poisson regression were used to compare differences in the inadequacy of prenatal care utilization. The percentage of inadequacy was higher in São Luís (34.6%) than in Ribeirão Preto (16.9%). Practically the same variables were associated with inadequacy in both cities. Puerperae with lower educational level, without a companion or cohabiting, who delivered in public health units, younger than 20 years, multiparae and smokers, with low family income presented higher percentages of inadequate prenatal care utilization. However, the effects of some variables differed between the two cities. The risk for inadequate use of prenatal care was higher for women attended in the public health sector in São Luís and for cohabiting women in Ribeirão Preto. The effect of the remaining factors studied did not differ between cities. The category of admission accounted for 57.0% of the difference in the inadequate use of prenatal care between cities and marital status accounted for 45.3% of the difference. Even after adjustment for all variables, part of the difference in the inadequacy of prenatal care utilization remained unexplained.

“…18,19 Several studies employing prenatal care use indices have demonstrated an association between inadequate prenatal care and preterm birth or LBW. [20][21][22][23] Our previous study (see Lin et al 24 ) found that in comparison with unaffected women, pregnant women with a history of depression made fewer prenatal care visits in Taiwan. However, to our knowledge, no study has attempted to investigate the association between the number of prenatal care visits and pregnancy outcomes in women with a history of depressive disorder.…”

Objective: To evaluate the quantity of prenatal care as a risk factor for giving birth to low birth weight (LBW), preterm, and small for gestational age (SGA) infants in a sample of women diagnosed with depressive disorder. Method:Our study used a population-based dataset, Taiwan's National Health Insurance Research Database, which we linked to Taiwan's birth certificate registry to identify a total of 5283 new mothers with depressive disorder. Multivariate logistic regression analyses were performed to measure the risk of giving birth to LBW, preterm, and SGA infants, relating to the number of prenatal care visits (10 or more, 8 to 9, and 7 or less) made by mothers with depressive disorder.Results: After adjusting for a woman's age, monthly income, urbanization level of place of residence, geographic location, marital status, substance abuse, arterial hypertension, diabetes, anemia, coronary heart disease, malpresentation, insufficient or excessive fetal growth, placenta or previa abruption, and infant's sex and parity, regression analyses revealed that mothers with a history of depressive disorder who received prenatal care 7 times or less were 4.21 (95% CI 3.34 to 5.32, P < 0.001), 5.37 (95% CI 4.33 to 6.67, P < 0.001), and 2.41 (95% CI 2.03 to 2.86, P < 0.001) times as likely to have LBW, preterm, and SGA babies, respectively, compared with mothers with depressive disorder who received prenatal care visits 10 times or more. Conclusions:Mothers with a history of depressive disorder who make fewer prenatal care visits were at an increased risk of LBW, SGA, and preterm birth, compared with women with a history of depressive disorder who made an adequate number of prenatal visits.Can J Psychiatry. 2011;56(5):273-280. Clinical Implications• Mothers with a history of depressive disorder who received 7 or less prenatal care visits had significantly higher percentages of LBW (20.0% compared with 5.2% compared with 8.7%), preterm (25.8% compared with 5.7% compared with 11.4%), and SGA (32.8% compared with 16.5% compared with 21.1%) births compared with women who received 10 or more and 8 to 9 prenatal care visits, respectively.• Mothers with a history of depressive disorder who received prenatal care 7 times or less were 4.21, 5.37, and 2.41 times as likely to have LBW, preterm, and SGA babies, respectively, compared with mothers with a history of depressive disorder who received prenatal care 10 times or more. Limitations• Administrative data are prone to a certain degree of coding errors and incomplete data, which may be random or contain systemic bias.• The disease severity and depression status were not available in the database.

Role of prenatal care in preterm birth and low birthweight in Portugal

Abstract: Our findings show that in a population with free access to prenatal care, the quantitative adequacy of prenatal care has an independent effect on pregnancy outcome, whether assessed through the occurrence of preterm births or low birthweight infants.
