    Abstract Introduction: Early infant diet might influence the risk of subsequent allergic disease.
    Methods: The Merthyr Allergy Prevention Study (MAPS) was a randomised controlled trial in infants at high risk of allergic disease. The trial determined whether a cow's milk exclusion diet for the first 4 months of life decreased the risk of allergic disease including asthma compared with a normal diet. A soya milk preparation was offered to those in the intervention group. A standardised questionnaire for allergic disease was completed at ages 1, 7, 15 and 23 years, with clinical assessment at 1, 7 and 23 years. The effect of the intervention on the risk of atopy, asthma and wheeze at age 23 years was determined.
    Findings: 487 subjects entered the study; at age 23 years 299 completed the questionnaire, of which 119 attended clinical assessment. Subjects randomised to the intervention group had a significantly increased risk of atopy (adjusted OR 2.97, 95% CI 1.30 to 6.80; p=0.01) and asthma (OR 2.07, 95%CI 1.09 to 3.91; p=0.03) at age 23 years, but not wheeze (OR 1.43, 95%CI 0.87 to 2.37; p=0.16). Earlier exposure to cow's milk was associated with a decreased risk of wheeze and asthma at age 23 years, while earlier exposure to soya milk was associated with an increased risk of atopy and asthma.
    Interpretation: In infants at high risk of allergic disease, either cow's milk exclusion or early soya milk introduction for the first 4 months of life increases the risk of atopy, wheeze and asthma in adulthood.

    Abstract Aims: Post-traumatic stress disorder (PTSD) is typically associated with high-risk population groups, but the risk of PTSD that is associated with trauma experienced in the community, and effect of changes in diagnostic criteria in DSM-5 on prevalence in the general population, is unknown.
    Methods: Cross-sectional analysis of population-based data from 4558 adults aged 25-83 years resident in Caerphilly county borough, Wales, UK. Exposure to different traumatic events was assessed using categorisation of free-text descriptions of trauma. PTSD caseness was determined using items assessing Diagnostic and Statistical Manual IV (DSM-IV) and DSM-5 A criteria and the Traumatic Screening Questionnaire.
    Results: Of the 4558 participants, 1971 (47.0%) reported a traumatic event. The most common DSM-IV A1 qualifying trauma was life-threatening illnesses and injuries (13.6%). The highest risk of PTSD was associated with assaultive violence [34.1%]. The prevalence of PTSD using DSM-IV A criteria was 14.3% (95% confidence interval [CI] = 12.8, 15.9%). Using DSM-5 A criteria reduced the prevalence to 8.0 (95% CI = 6.9, 9.4%), primarily due to exclusion of DSM-IV A1 qualifying events, such as life-threatening illnesses.
    Conclusions: Nearly one-half of a general community sample had experienced a traumatic event and of these around one in seven was a DSM-IV case of PTSD. Although the majority of research has concentrated on combat, rape and assaultive violence, life threatening illness is a more common cause of PTSD in the community. Removal of this traumatic event in DSM-5 could reduce the number of cases of PTSD by around 6.0%.

    Abstract Background: Coronary heart disease (CHD) mortality in England fell by 36% between 2000 and 2007 and it is estimated that approximately 50% of the fall was due to improved treatment uptake. Marked socio-economic inequalities in CHD mortality in the United Kingdom (UK) remain, with higher age-adjusted rates in more deprived groups. Inequalities in the persistence of medication for primary and secondary prevention of CHD may contribute to the observed social gradient and we investigated this possibility in the population of Wales (UK).
    Methods and findings: An electronic cohort of individuals aged over 20 (n = 1,199,342) in Wales (UK) was formed using linked data from primary and secondary care and followed for six years (2004-2010). We identified indications for medication (statins, aspirin, ACE inhibitors, clopidogrel) recommended in UK National Institute for Clinical Excellence (NICE) guidance for CHD (high risk, stable angina, stable angina plus diabetes, unstable angina, and myocardial infarction) and measured the persistence of indicated medication (time from initiation to discontinuation) across quintiles of the Welsh Index of Multiple Deprivation, an area-based measure of socio-economic inequality, using Cox regression frailty models. In models adjusted for demographic factors, CHD risk and comorbidities across 15 comparisons for persistence of the medications, none favoured the least deprived quintile, two favoured the most deprived quintile and 13 showed no significant differences.
    Conclusions: During our study period (2004-2010) we found no significant evidence of socio-economic inequality in the persistence of recommended medication for primary and secondary prevention of CHD.

  9. Article ; Online: Equity in healthcare for coronary heart disease, Wales (UK) 2004-2010: A population-based electronic cohort study.

    Abstract Background: Despite substantial falls in coronary heart disease (CHD) mortality in the United Kingdom (UK), marked socioeconomic inequalities in CHD risk factors and CHD mortality persist. We investigated whether inequity in CHD healthcare in Wales (UK) could contribute to the observed social gradient in CHD mortality.
    Methods and findings: Linking data from primary and secondary care we constructed an electronic cohort of individuals (n = 1199342) with six year follow-up, 2004-2010. We identified indications for recommended CHD interventions, measured time to their delivery, and estimated risk of receiving the interventions for each of five ordered deprivation groups using a time-to-event approach with Cox regression frailty models. Interventions in primary and secondary prevention included risk-factor measurement, smoking management, statins and antihypertensive therapy, and in established CHD included medication and revascularization. For primary prevention, five of the 11 models favoured the more deprived and one favoured the less deprived. For medication in secondary prevention and established CHD, one of the 15 models favoured the more deprived and one the less deprived. In relation to revascularization, six of the 12 models favoured the less deprived and none favoured the more deprived-this evidence of inequity exemplified by a hazard ratio for revascularization in stable angina of 0.79 (95% confidence interval 0.68, 0.92). The main study limitation is the possibility of under-ascertainment or misclassification of clinical indications and treatment from variability in coding.
    Conclusions: Primary care components of CHD healthcare were equitably delivered. Evidence of inequity was found for revascularization procedures, although this inequity is likely to have only a modest effect on social gradients in CHD mortality. Policymakers should focus on reducing inequalities in CHD risk factors, particularly smoking, as these, rather than inequity in healthcare, are likely to be key drivers of inequalities in CHD mortality.

    Abstract We have taken advantage of a natural experiment to measure the impact of the phased abolition of prescription co-payments in Wales. We investigated 3 study periods covering the phased abolition: from £6 to £4, £4 to £3, and £3 to £0. A difference-in-difference modelling was adopted and applied to monthly UK general practice level dispensing data on 14 selected medicines which had the highest percentage of items dispensed subject to a co-payment prior to abolition. Dispensing from a comparator region (North East of England) with similar health and socio-economic characteristics to Wales, and where prescription co-payments continued during the study periods, was used to isolate any non-price effects on dispensing in Wales. Results show a small increase in dispensing of 14 selected medicines versus the comparator. Compared with NE England, monthly average Welsh dispensing was increased by 11.93 items (7.67%; 95% CI [7.2%, 8.1%]), 6.37 items (3.38%; 95% CI [2.9%, 3.7%]) and 9.18 items (4.54%; 95% CI [4.2%, 4.9%]) per practice per 1,000 population during the periods when co-payment was reduced. Price elasticities of the selected medicines utilisation were -0.23, -0.13, and -0.04 in 3 analyses, suggesting the abolition of co-payment had small effect on Welsh dispensing.
