  • Present self-reported physical activity and objective physical activity in the future
    Tomoyuki Kawada

    Hamer et al. conducted a 13-year longitudinal study on the predictive ability of self-reported physical activity on physical activity measured by accelerometers (1). Participants were 394 healthy men and women aged 54 years on average. They concluded that the habits of physical activity in adulthood are partly tracked into older age. About their attractive report, I have several concerns on their statistical outcomes....

  • Traffic Pollution may Increase Testosterone which may Increase Preeclampsia
    James M. Howard

    "Traffic-related pollution," especially diesel combustion produced, may be shown to increase testosterone. It is my hypothesis that increased maternal testosterone increases preeclampsia (http://anthropogeny.com/Incresing%20Testosterone%20and%20Preeclampsia.htm ).

    I suggest the findings of Pereira, et al., may be explained by increased maternal testosterone.

  • Family meals boost children's 5 A Day
    C Albert Yeung

    We all know eating together as a family can boost conversation, foster closeness and encourage healthy ways with food. However, a 2011 survey of 1354 people for the insurance firm Cornish Mutual found 48% of British households do not share a meal every day. [1]

    This study shows that by having a family dinner together it can increase children's daily fruit and vegetable intake to reach the 5 A Day target. It rei...

  • Policy, evidence and theory; contextualising a glossary of policymaking
    Kathryn A Oliver

    We welcome the glossary of theories presented last month by Smith & Katikireddi (2012) and applaud the intention to introduce wider thinking from the political sciences on these subjects to health researchers. Drawing on our practical experiences in the fields of healthcare management and health services research, we would like to identify three related areas which may also be useful for the public health audience....

  • Family meals boost children's 5 A Day

    We all know eating together as a family can boost conversation, foster closeness and encourage healthy ways with food. However, a 2011 survey of 1354 people for the insurance firm Cornish Mutual found 48% of British households do not share a meal every day. [1]

    This study shows that by having a family dinner together it can increase children's daily fruit and vegetable intake to reach the 5 A Day target. It reinforces the view that children learn more from what adults do than what they say, therefore it is the parental role modelling that helps shape their future habits.

    The strengths of this study are its large sample size (2383 children) and reliable methods of assessing dietary intake through a validated food intake tool. However, there are limitations which have not been noted by the researchers.

    This is a single sample of London schoolchildren taking part in trials assessing school gardening and diet. We do not know whether the children who were taking part in this trial may have particular characteristics that make them different from, for example, children selected from a completely ra...

  • Policy-as-discourse - an additional theory that makes for a more comprehensive glossary
    Sara E Shaw

    Dear Editor

    In their recent paper, Smith and Katikireddi (2012) provide a useful outline of theories for understanding policymaking. The article is aimed at public health practitioners and researchers who are seeking to shape policy. It rightly encourages them to draw on relevant theory to more productively guide their interactions with, and potential influence on, relevant policy. This is a timely and welcome...

  • What leads to a healthy ageing and longevity?
    Ivy Shiue
    It is with great interest we read "Frequent shopping by men and women increases survival in the older Taiwanese population" by Chang et al.1 The authors have found that highly frequent shopping compared to never or rarely is likely to predict survival as it captures several dimensions of personal well-being, health and security as well as contributing to the community's cohesiveness and economy. The significance has remained after...

  • Validity of self-reported prevalent cases of stroke and acute myocardial infarction in the Spanish cohort of the EPIC study
    Siamak Sabour

    The aim of the authors was to assess the validity and agreement of self-reported prevalent cases of stroke and AMI in the Spanish cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC). They calculated sensitivity, specificity, positive predictive values and ? statistics. The sensitivity of self-reported prevalent cases of stroke was 81.3% and that for AMI was 97.7%. The positive predictive value...

  • Health inequalities and IMR
    Rosemary J Brown

    I was interested to read your letter/article in the Journal of Epidemiology and Community Health, and your conclusion that there were significant reductions in IMR. You wondered whether this might have been due to interventions such as Sure Start and the Health in Pregnancy grant. I would be surprised if the latter played any significant part, as it came far too late in pregnancy to do anything significant and, anecdotally...

  • "Green cities and mortality: is migration the answer?"
    Sonam O Lasopa

    Numerous studies conducted have found evidence for a positive relation between green space in peoples environment and self reported indicators of morbidity and mortality (Lee and Maheswaran, 2011). The authors in this study have found mortality from all causes to be higher in greener cities. Attempts have been made to adjust for factors which may act as confounders, however other community level factors have not been tak...
