Socio-demographic and consanguinity risk factors associated with low birthweight.

OBJECTIVE: To examine socio-demographic and biological risk factors associated with mothers giving birth to a low birthweight newborn among Arab women in Qatar. METHODS: The case-control study was conducted at two main tertiary hospitals in Qatar in which participants were prospectively identified from January 2010 to April 2011. Data were collected by survey on maternal ethnicity, age, education, socioeconomic status, body mass index, consanguinity and gestational age. A total of 16,500 newborns were screened for low birthweight. A total of 863 mothers of low birthweight cases and an equal number of mothers of normal-weight babies were studied. RESULTS: Qatari mothers were found to be 1.2 times as likely to have a low birthweight (< 2500g) newborn compared to other Arab women (p < 0.057). Mothers with a primary school education were 1.6 times as likely as university educated mothers to have a low birthweight newborn (p < 0.006). Likewise, obese mothers were 1.5 times as likely as their normal-weight counterparts (p < 0.009). Consanguineous couples who were first-degree cousins were 1.9 times as likely as non-related couples to have a low birthweight newborn (p < 0.001). Newborns with a gestational age of < 37 weeks were 19.6 times as likely as those > or = 37 weeks to have a low birthweight (p < 0.001). CONCLUSION: The majority of the risk factors associated with low birthweight were modifiable. Health education campaigns need to target the most vulnerable groups to reduce the rates of low birthweight among Arabs in Qatar.

The impact of the interpregnancy interval on birth weight and other pregnancy outcomes / O impacto do intervalo entre gestações no peso de recém-nascidos e outros desfechos da gravidez

To investigate the relationship between the interpregnancy interval and low birth weight and other pregnancy outcomes. METHODS: this case-control study was carried out in hospitals from January 2010 to April 2011. For cases, mothers of 1216 newborns with birth weight<2500 g were approached and 854 mothers participated (70.2 percent). For controls, mothers of 1158 newborns with >2500 g were approached and 854 mothers participated in this study (73.7 percent). Face-to-face interviews were conducted to complete the questionnaires. RESULTS: of the newborn babies with low birth weight, the risk was higher among mothers with a short interpregnancy interval (40.3 percent), whereas for infants with normal birth weight, the majority of the mothers had a longer interpregnancy interval of 24 months (44.7 percent). A short interpregnancy interval of 612 months was more common among women of <25years (49.4 percent; p<0.001) and those who were illiterate (13.1 percent; p=0.043) with a higher risk of low birth weight compared to the controls. Prenatal care during the 1st trimester was lower in women with low birth weight children (p<0.001). Normal delivery was observed less in women with a short birth interval among cases (58.7 percent) compared to controls (79 percent) (p=0.001). A J-shaped association was observed between low birth weight and the interpregnancy interval. CONCLUSIONS: a short interpregnancy interval is associated with an increased risk of low birth weight, especially in younger and illiterate women...

Investigar a relação entre o intervalo entre gestações e o baixo peso de recém-nascidos e outras conseqüências da gestação. MÉTODOS: este estudo caso-controle foi realizado em hospitais entre janeiro de 2010 e abril de 2011. Dentre as mães dos 1216 recém-nascidos com peso <2500 g, 854 (70,2 por cento) aceitaram participar do estudo de caso. No grupo controle, dentre as mães dos 1158 recém-nascidos com peso > 2500 g, participaram 854(73,7 por cento). Para completar os questionários, foram conduzidas entrevistas face a face. RESULTADOS: dos recém-nascidos com baixo peso, o fator de risco foi mais alto entre as mães com curto intervalo intergestacional (40,3 por cento), enquanto para recém-nascidos com peso normal a maioria das mães tinham uma boa margem de intervalo intergestacional de 24 meses (44,7 por cento). Curtos intervalo intergestacional (6 a 12 meses) foi mais comum entre mulheres de <25 anos (49,4 por cento; p<0,001) e analfabetas (13,1 por cento; p=0,043), com mais alto risco de baixo peso quando comparado aos controle. Cuidados pre-natais durante o primeiro trimestre foi menor nas mulheres com crianças de baixo peso (p<0,001). Menos partos normais foi observado em mulheres com curtos intervalos de nascimento para os casos (58,7 por cento) comparados aos controles (79 por cento) (p=0,001). Uma associação não monotônica tipo função J, foi observada entre o baixo peso e intervalo intergestacional. CONCLUSÕES: um curto intervalo entre gestações é associado a um risco maior de nascerem bebês de baixo peso, principalmente entre mulheres mais jovens e analfabetas...

Do we need to maximise the breast cancer screening awareness? Experience with an endogamous society with high fertility.

BACKGROUND: In the State of Qatar, breast cancer has become the most common form of cancer among women. The aim of this study was to explore knowledge, attitude and practice about breast cancer and to identify potential barriers to screening procedures among women. METHODS: This multistage sampling cross sectional survey in primary health care centers and the outpatient department of the Women's Hospital in the State of Qatar targeted a representative sample of 1,200 Qatari women aged between 30 to 55 years of age during the period from December 2008 to April 2009. A total 1,002 subjects (83.5%) consented to participation. Face to face interviews were conducted with a designed questionnaire covering knowledge about breast cancer, attitudes and practices of breast cancer screening. Socio-demographic variables were included. RESULTS: The majority of Qatari women demonstrated an adequate knowledge about breast cancer, with a significant relation to education status. Almost three quarters were aware that breast cancer is the most common cancer in women. A good proportion knew that nipple retraction (81.2%) and discharge of blood (74.6%) are warning signs. Of the studied Qatari women, 24.9% identified breast self examination, 23.3% clinical breast examination (CBE) and 22.5% mammography as methods for detection of breast cancer. The frequently reported barriers among the Qatari women were asking any doctor/nurse how to perform breast self examination (57.3%), embarrassment about CBE (53.3%) and fear of mammography results (54.9%). Univariate and multivariate logistic regression analysis showed that family history, level of education, living in an urban area and having medical check-ups when healthy were significant predictors for CBE and mammography. CONCLUSION: The study findings revealed that although Qatari women had adequate general knowledge about breast cancer, the screening rates for BSE, CBE and mammography were low, these being performed most frequently by young Qatari women with a higher level of education.
