D C Greenwood et al, 2014, Caffeine intake during pregnancy and adverse birth outcomes: a systematic review and dose-response meta-analysis. European Journal of Epidemiology, published online ahead of print.

Caffeine is commonly consumed during pregnancy, crosses the placenta, with fetal serum concentrations similar to the mother’s, but studies of birth outcome show conflicting findings. We systematically searched Medline and Embase for relevant publications. We conducted meta-analysis of dose-response curves for associations between caffeine intake and spontaneous abortion, stillbirth, preterm delivery, low birth weight and small for gestational age (SGA) infants. Meta-analyses included 60 unique publications from 53 cohort and case-control studies. An increment of 100 g caffeine was associated with a 14 % (95 % CI 10-19 %) increase in risk of spontaneous abortion, 19 % (5-35 %) stillbirth, 2 % (-2 to 6 %) preterm delivery, 7 % (1-12 %) low birth weight, and 10 % (95 % CI 6-14 %) SGA. There was substantial heterogeneity in all models, partly explained by adjustment for smoking and previous obstetric history, but not by prospective assessment of caffeine intake. There was evidence of small-study effects such as publication bias. Greater caffeine intake is associated with an increase in spontaneous abortion, stillbirth, low birth weight, and SGA, but not preterm delivery. There is no identifiable threshold below which the associations are not apparent, but the size of the associations are generally modest within the range of usual intake and are potentially explained by bias in study design or publication. There is therefore insufficient evidence to support further reductions in the maximum recommended intake of caffeine, but maintenance of current recommendations is a wise precaution.

X Li et al, 2014, Coffee consumption and hip fracture risk: a meta-analsyis, Journal of Nutritional Science, published online ahead of print.

ABSTRACT
To investigate the effect of coffee consumption on hip fracture risk, a meta-analysis was conducted. The PubMed database was screened for all published studies about coffee consumption and hip fracture through to November 2011. Reviews, PubMed option ‘related articles’ and references of retrieved papers were also searched for potentially relevant papers. Only studies that contained OR with 95 % CI for the association between coffee consumption and hip fracture risk were included. The summary risk estimates were calculated by fixed- and random-effects models. Subgroup analyses were carried out stratified by study designs and participant characteristics, respectively. A total of six prospective cohort studies and six case-control studies were included in the final analysis. The pooled OR displayed increased risk of hip fracture by 29·7 % (95 % CI 0·960, 1·751; P = 0·09) for the highest compared with the lowest coffee consumption by the random-effects model (P for heterogeneity = 0·000; I (2) = 84·0 %), but the result had no statistical significance. Subgroup analyses showed that coffee consumption significantly increased hip fracture risk by 54·7 % (95 % CI 1·152, 2·077; P = 0·004) among women, by 40·1 % (95 % CI 1·015, 1·935; P = 0·040) for elderly participants aged over 70 years, and by 68·3 % for Northern Americans (95 % CI 1·492, 1·899; P = 0·000). Other subgroup analyses according to data published before the year 2000 showed a positive association between coffee and hip fracture risk, and follow-up duration also positively affected hip fracture risk, especially when the follow-up length was less than 13 years. Although our meta-analysis has provided insufficient evidence that coffee consumption significantly increases hip fracture risk, coffee intake may increase hip fracture risk among women, elderly participants and Northern Americans. No dose-response pattern was observed.

Espresso Voyeurism: Naked Extraction in a Bottomless Portafilter

Gábor Laczkó is an obsessive tinkerer of existing coffee coffee equipment. We first encountered Laczkó, who runs the Hungarian roastery Kávékalmár, when he sent us this video of a moka pot rigged with all manner of cables, sensors, a scale and a a YCT 474UD Thermometer/datalogger. That project represented months of experimentation, all of which Laczkó says led to proof […]

S S Mirza et al, 2014, Coffee consumption and incident dementia, European Journal of Epidemiology, published online.

ABSTRACT

Coffee consumption has been frequently reported for its protective association with incident dementia. However, this association has mostly been reported in studies with short follow-up periods, and it remains unclear to what extent reverse causality influences this association. Studying the long-term effect of coffee consumption on dementia with stratified follow-up time may help resolve this issue. In the population-based Rotterdam Study, coffee consumption was assessed in 1989-1991 (N = 5,408), and reassessed in 1997-1999 (N = 4,368). Follow-up for dementia was complete until 2011. We investigated the association of coffee consumption and incident dementia for the two examination rounds separately using flexible parametric survival models. We studied the entire follow-up period as well as stratified follow-up time at 4 years. For both examination rounds, we did not find an association between coffee consumption and dementia over the entire follow-up. In contrast, for both examination rounds, a protective association was observed only in the follow-up stratum of 0-4 years. Our data suggest that coffee consumption is not associated with incident dementia during long-term. The protective association observed in the short-term might be driven by reverse causality.

A Crippa et al, 2014. Coffee Consumption and Mortality from All Causes, Cardiovascular Disease, and Cancer: A Dose-Response Meta-Analysis, American Journal of Epidemiology, published online ahead of print.

ABSTRACT

Several studies have analyzed the relationship between coffee consumption and mortality, but the shape of the association remains unclear. We conducted a dose-response meta-analysis of prospective studies to examine the dose-response associations between coffee consumption and mortality from all causes, cardiovascular disease (CVD), and all cancers. Pertinent studies, published between 1966 and 2013, were identified by searching PubMed and by reviewing the reference lists of the selected articles. Prospective studies in which investigators reported relative risks of mortality from all causes, CVD, and all cancers for 3 or more categories of coffee consumption were eligible. Results from individual studies were pooled using a random-effects model. Twenty-one prospective studies, with 121,915 deaths and 997,464 participants, met the inclusion criteria. There was strong evidence of nonlinear associations between coffee consumption and mortality for all causes and CVD (P for nonlinearity < 0.001). The largest risk reductions were observed for 4 cups/day for all-cause mortality (16%, 95% confidence interval: 13, 18) and 3 cups/day for CVD mortality (21%, 95% confidence interval: 16, 26). Coffee consumption was not associated with cancer mortality. Findings from this meta-analysis indicate that coffee consumption is inversely associated with all-cause and CVD mortality.
