This may be because the body releases a hormone called cortisol in response to stress. High levels of cortisol from long-term stress may be the mechanism behind how stress can increase cholesterol.

We summarize these data. Review Methods Selection of studies and literature searches For selected publications we examined abstracts, and where necessary full text, to find studies satisfying these inclusion criteria: Papers cited by Maeda et al. New papers were then sought from Collaborative Trials within the Cochrane Library using the same keywords, from reference lists in accepted papers, and from an ongoing project on white blood cell changes submitted for publication.

The selected papers were then separated into studies, further study details being obtained from additional references if required. Data entry Relevant data were entered onto a study and a change database, each study being identified by a 6-letter reference REF. The study database contains one record per study describing study attributes. The change database contains one or more records per study, describing estimates of HDL-C change from baseline. Study attributes recorded include relevant publications, sexes considered, age range, location, years of start, finish and publication, length of follow-up, study design, nature of population studied including smoking and medical criteriastudy size, HDL-C measurement method, fasting or smoking abstinence requirements before measurement, diet or exercise modification during follow-up, and confounding and stratifying variables considered.

Details on the change database include smoking status quitter, continuing smoker, never smokersmoking habits at baseline and follow-up products, cigarette types, amount smokedbiochemical validation methods, intra-measurement period, original measurement unit, data source, and population the data applies to sex, age, intervention groups. Also recorded is information on the HDL-C change itself mean change, or mean level at both baseline and follow-upits variability confidence limits, SD, SE, N, significance of change and whether the change estimate was direct, or relative to never smokers or to continuing smokers.

Change data were entered for never smokers, continuing smokers and quitters, but not for smokers who quit during the follow-up period but resumed before the second HDL-C measurement. Sex-specific data were preferred to combined-sex data. Data stratified on other variables were entered in addition to overall data, including stratification by later resumption of smoking, where available from studies with multiple follow-ups.

Available information on baseline weight, body mass index BMI and other commonly reported physiological parameters, and on change in weight and BMI, was also recorded. Statistical analysis For trials giving results for subjects continuously abstinent since baseline, the quit time was taken as the intra-measurement period.

For other trials, it was estimated from the study design details.

For observational studies, where quitting could have occurred any time in an interval, the quit time was estimated based on the interval midpoint. Non-stratified data were generally selected for analysis if available, with certain exceptions.
