Studies have shown a positive association between trans fatty acids (TFA) intake and risk of coronary heart disease (CHD), primarily accounted for by industrially produced TFA. Some of these studies indicate an inverse association between ruminant TFA (R-TFA) intake and CHD implying that R-TFA intake is innocuous or even protective against CHD. The aim of this study was to describe the association between R-TFA intake and risk of CHD evaluating both the absolute and the energy-adjusted intake. ⋯ This study suggests that R-TFA intake is not associated with a higher risk of CHD. Whether R-TFA intake is even protective against CHD among women cannot be concluded from this study.

Socio-economic inequalities in health within countries are a key public health issue. It is important that we can effectively make international comparisons of the level of inequalities and assess trends over time. We investigate how the results of such comparisons can differ depending on whether inequality is quantified using the rate ratio or rate difference. ⋯ The results of comparisons of the magnitude of health inequalities between countries and over time depend upon whether the rate ratio or rate difference is used. When statements are made comparing the size of inequalities it should be made completely clear whether these are measured on an absolute or relative scale. If the substantive conclusions differ according to the measure used this should be clearly stated. In this situation emphasis should only be given to results based on one summary measure if this can be clearly and explicitly justified in the context.

The impact of media reporting of suicides of entertainment celebrities may affect suicide rates due to an imitation effect. We investigated the impact on suicides of the media reporting of the suicide of a male television celebrity. ⋯ The extensive media reporting of the celebrity suicide was followed by an increase in suicides with a strong implication of a modelling effect. The results provide further support for the need for more restrained reporting of suicides as part of suicide prevention strategies to decrease the imitation effect.
