Dietary intake during pregnancy may influence child neurodevelopment and cognitive function. This study aims to investigate the associations between dietary patterns obtained in pregnancy and intelligence quotients (IQ) among offspring at 8 years of age. Pregnant women enrolled in the Avon Longitudinal Study of Parents and Children completed a food frequency questionnaire at 32 weeks' gestation ( n = 12,195). Dietary patterns were obtained by cluster analysis. Three clusters best described women's diets during pregnancy: 'fruit and vegetables,' 'meat and potatoes,' and 'white bread and coffee.' The offspring's IQ at 8 years of age was assessed using the Wechsler Intelligence Scale for Children. Models, using variables correlated to IQ data, were performed to impute missing values. Linear regression models were employed to investigate associations between the maternal clusters and IQ in childhood. Children of women who were classified in the meat and potatoes cluster and white bread and coffee cluster during pregnancy had lower average verbal (β = −1.74; p < .001 and β = −3.05; p < .001), performance (β = −1.26; p = .011 and β = −1.75; p < .001), and full-scale IQ (β = −1.74; p < .001 and β = −2.79; p < .001) at 8 years of age when compared to children of mothers in the fruit and vegetables cluster in imputed models of IQ and all confounders, after adjustment for a wide range of known confounders including maternal education. The pregnant women who were classified in the fruit and vegetables cluster had offspring with higher average IQ compared with offspring of mothers in the meat and potatoes cluster and white bread and coffee cluster.

Objectives Willingness-to-pay ( WTP) provides a broad assessment of well-being, capturing benefits beyond health. However, the validity of the approach has been questioned and the evidence relating to the sensitivity of WTP to changes in health status is mixed. Using menorrhagia (heavy menstrual bleeding) as a case study, this exploratory study assesses the sensitivity to scale of WTP to change in health status as measured by a condition-specific measure, MMAS, which includes both health and non-health benefits. The relationship between EQ-5D and change in health status is also assessed. Methods Baseline EQ-5D and MMAS values were collected from women taking part in a randomized controlled trial for pharmaceutical treatment of menorrhagia. Following treatment, these measures were administered along with a WTP exercise. The relationship between the measures was assessed using Spearman's correlation analysis, and the sensitivity to scale of WTP was measured by identifying differences in WTP alongside differences in MMAS and EQ5D values. Results Our exploratory findings indicated that WTP, and not EQ-5D, was significantly positively correlated with change in MMAS, providing some evidence for convergent validity. These findings suggest that WTP is capturing the non-health benefits within the MMAS measure. Mean WTP also increased with percentage improvements in MMAS, suggesting sensitivity to scale. Conclusion When compared to quality of life measured using the condition-specific MMAS measure, the convergent validity and sensitivity to scale of WTP is indicated. The findings suggest that WTP is more sensitive to change in MMAS, than with EQ-5D. [ABSTRACT FROM AUTHOR]

Background Behavioural change interventions for persons with chronic illness draw on a variety of theoretical approaches including motivational interviewing and shared decision making. Health literacy provides an additional, potentially powerful explanatory framework to guide research and practice. Objective To examine the changes in the depth and detail of diabetes-related knowledge and confidence for persons with type 2 diabetes. Design Two-year, prospective, observational study, using questionnaire data at two time points (baseline and 2 years later) and in-depth interviews with a theoretically selected subsample. Setting and participants A total of 319 patients initially recruited from a deprived urban area in north-west England Intervention Dedicated tele-carer education and support, tailored to the individual circumstances of the patient. Main outcome measures Perceptions of confidence, levels of empowerment, learning for self-care and most helpful aspects of the intervention. Results Over 90% expressed confidence in keeping their blood sugar controlled, and high levels of perceived empowerment (mean = 4.25; 95% CI, 4.17-4.33) were found. Changes in the depth and detail of diabetes-related knowledge and confidence, from the specific to the more general, were observed and enhanced competence in translating knowledge into practice. Discussion and conclusions The intervention, built within a developed working partnership between tele-carer and patient, operated at two levels: health literacy, enhancing knowledge, developing personal skills and enabling self-control; and socio-psychological behavioural change, tailored to individuals within their socio-economic environments, enabling increased motivation and supportive problem-solving. Both approaches find reflection in the findings and provide powerful explanatory lenses to interrogate the data. [ABSTRACT FROM AUTHOR]

Objective To determine the preferred means by which participants in a study of cardiac rehabilitation wish to be informed of the study’s results. Design Postal questionnaire survey of participants in a randomized controlled trial. Setting Cornwall, southwest England. Participants Patients recruited to the Cornwall Heart Attack Rehabilitation Management Study (CHARMS). Method Participants recruited to CHARMS who were alive 3 years and 9 months after the trial was completed were contacted by letter and invited to return a reply slip with four short questions indicating how they would prefer to be informed about the published results of the study. Results In March 2008, 191/230 participants originally recruited to CHARMS were still alive. General practitioners deemed 166/191 (88%) survivors medically appropriate to be contacted through a postal survey, and 154/166 (93%) participants responded to the invitation to participate in the follow-up survey. 86% (143/166) of participants indicated that they wished to be informed about the results: 115 (80%) of these elected to receive information by letter and 25 (18%) of these preferred to attend a meeting. Men older than 65 years predominated in this latter group. Women respondents preferred to receive the study results by letter; none preferred communication by email or the web. Conclusion Survivors of acute myocardial infarction who participated in a RCT of cardiac rehabilitation wanted to receive a summary of the aggregate study results. Participants had preferences regarding how they would wish to be informed about the results of the study. Most participants preferred to be informed by letter or email, but some preferred the interaction of a group or a meeting. [ABSTRACT FROM AUTHOR]
