  • Is it wise to balance on a high-wire?
    Jan P. Siedentopf

    Based on a large set of data, the authors report on a positive effect of alcohol consumption in pregnancy on the balance ability of exposed children. In their study, information on alcohol consumption was acquired during pregnancy, probably making this data more reliable than other large studies on the effect of prenatal alcohol exposure, eg. the "UK Millennium Cohort Study" reported on by Kelly et al.(1).

  • Re:Salt: the need for government action
    Feng J He

    We agree with Professor Norman Temple, that a legislative approach to salt reduction will be quicker and more effective than the voluntary approach. However, the harsh reality is that it is extremely unlikely that governments will support a legislative approach in the majority of developed countries given the huge power of the food industry. For example, in the United States, it has been strongly recommended since the 197...

  • The data in the appendix provide a different perspective
    Elizabeth Bernstein

    To the editor,

    I am not a health care professional, but a mother who brought my babies into my bed a couple of decades ago when it appeared that that was the best way for me to get enough rest to be able to care for them. I have read with interest the recent meta-analysis by Carpenter et al. concluding that bed-sharing increases the risk of SIDS even in the case of breast- feeding, non-smoking mothers. [1]

  • Salt: the need for government action
    Norman J. Temple

    Brinsden and colleagues1 describe the decrease in the salt content of bread sold in the UK. They see this as evidence of success for the policy of voluntary agreements with the food industry. In actuality, a careful assessment of the facts and figures given in their paper reveals the failure of the policy.

    Between 2001 and 2011 salt intake by adults in the UK fell by about 15%, i.e., from 9.5 to 8.1 g/day. The t...

  • Dietary alpha-linolenic acid intake and prostate cancer risk: A dose-response analysis of observational studies
    Long Zhai

    Abstract Alpha-linolenic acid (ALA) consumption has been linked to risk of prostate cancer theoretically, but the findings were conflicting from observational studies. Results from recent meta-analysis suggested a small risk, moderate protective and no effect of alpha-linolenic acid consumption on prostate cancer risk. However, the relationship, if exists, between alpha-linolenic acid consumption and prostate cancer ris...

    Dear Sir,

    We read with interest the recent analysis of five large case-control studies involving sudden infant death syndrome (SIDS) with respect to bed sharing [1]. Our concern is that the possibility of accidental suffocation was n...

  • Concerning conclusions that may negatively impact on safe sleeping, successful breastfeeding, parent wellbeing and open communication between health professionals and parents
    Catherine M. Fetherston

    Dear Editor,

    The paper published in your journal by Carpenter et al [1], claims to resolve uncertainties associated with bedsharing and SIDS. We believe however, it does little other than fuel further confusion in the minds of parents and the health professionals charged with providing them with information and support.

    As outlined in other letters the authors chose to use a selection of older studies...

  • More questions than answers
    Herbert Renz-Polster

    Dear Editor,

    This publication [1] is confusing to parents and physicians because it draws far reaching conclusions from unconvincing data.


    In our opinion, the validity of this analysis is threatened by selection bias, imputation bias and presentation bias. We think that the conclusions drawn from this study are not generalizable and that many current issues pert...

  • Sedentary Behaviour in adults and cardiovascular risk: Letter to editor
    Simran Kaur

    Cardiovascular risk study was carried by Heinonnen et al to establish an association between sedentary lifestyle and cardiovascular risk in young adults. Although due to its cross sectional design, it cannot be extrapolated to address the causality of findings. Nevertheless, it is indeed a good piece of research wherein all confounders except television viewing, which is a growing practice, are accounted for. However, thi...
