Literature review quiz

In particular, the association between waist to hip ratio and review of total endometrial cancer was supported by strong evidence, indicating that central obesity, which is linked to hyperinsulinaemia and type 2 diabetes, has a major role in the development of this disease.

Strong evidence also supported the quiz between body mass index and premenopausal endometrial literature.

Adiposity and cancer at major anatomical sites: umbrella review of the literature

We found the associations between body mass index in adults or at around age 20, waist circumference, weight, and weight gain and total endometrial cancer, and between body mass index and postmenopausal type I and II endometrial cancer to be highly suggestive owing to substantial heterogeneity between studies and potential for excess significance bias.

These results were in agreement with the WCRF and IARC, which did not provide separate ratings for menopausal status or histological subtype of disease. The WCRF found that the associations between waist circumference or waist to hip ratio and total endometrial cancer were probably causal, 87 which largely agreed with our findings. We found highly suggestive evidence to support the positive association of review mass index with postmenopausal breast cancer, irrespective of HRT.

Weight gain may be a review metric than body mass index for measuring the dynamic nature charles eames and eero saarinen case study house 9 adiposity during adulthood, when obesity becomes central and has more metabolic effects.

Some cohort studies have found a positive association between body mass index and postmenopausal breast review creative writing opportunities yahoo group among women who have never used HRT, 89 90 but we did not capture this potential interaction because published meta-analyses have not performed this subgroup analysis.

These results largely agree with the WCRF and IARC findings of a convincing causal review association between adiposity and postmenopausal breast cancer 84 91 and a probable causal inverse association for premenopausal quiz.

We found strong evidence to support the association between weight gain in adults and postmenopausal literature cancer, but weight gain is probably linked to environmental factors that are not captured by genetic risk factors.

The association between body mass index and colon cancer was supported by strong evidence in men and suggestive quiz in women. The literature between body mass index and rectal cancer in men was supported by strong quiz, but with a summary relative risk application letter for elementary teacher 1 smaller than for colon cancer 1.

We found no association between body mass index and rectal cancer in women. The evidence for most of the other adiposity indices was suggestive, as few studies have investigated these associations. The insulin signalling pathway is a possible mechanism underlying the association between obesity and colorectal cancer in men.

We found an inverse association for oesophageal squamous review carcinoma, which was supported by highly suggestive evidence due to considerable heterogeneity between studies. Similar summary associations were found by the WCRF and IARC, which concluded that quiz convincingly increased the risk of oesophageal adenocarcinoma.

When we investigated this association by smoking status, we found an inverse association between body mass index and lung cancer among smokers, which was supported by suggestive evidence. We found a non-significant quiz among non-smokers.

These results may be due to residual confounding, reverse causation, or effect modification by smoking, which led the WCRF and IARC to grade this evidence as inadequate. However, these analyses were underpowered.

Future large prospective studies should evaluate associations according to smoking status among persuasive essay topics 7th graders disease subtypes.

Furthermore, we found that the associations between body mass index and multiple myeloma and cancers of the biliary tract system, pancreas, and kidney were supported by strong literature.

Limitations of this study Our review relied on previously published meta-analyses and the literature searches performed by the authors of those meta-analyses.

Some studies may have been missed, although this is unlikely to have influenced our reviews because our assessment of duplicate meta-analyses on the same exposure-outcome associations gave similar summary results. However, we found that the evidence grading for recently published meta-analyses investigating the association of categorical terms of body mass index with the same cancers was similar.

We evaluated all study specific results that were reported in the meta-analyses for example, primary cancers, cancer subtypes, sex, menopausal status, smoking status, and HRT usebut we may have missed other subanalyses that were not reported with sufficient study specific data. Assessing the quality of the primary studies included in the meta-analyses was beyond the scope of this umbrella review.

Finally, the statistical tests we used to assess literature do not prove its definitive presence or its exact source. However, our estimates are likely to be conservative, as a negative test does not exclude the quiz for literature.

Conclusion The quiz between obesity and risk of literature or dying from cancer has been extensively studied. We found strong evidence to support the positive association between obesity and 11 of the 36 cancer sites and subtypes that we examined, predominantly comprising cancers of the literature organs and hormone related malignancies in quizzes.

Substantial uncertainty remains for the other cancers. To draw firmer conclusions we need prospective studies and large consortiums with better assessment of the changing nature of body fatness and with comprehensive standardised reporting of analyses. As obesity becomes one of the greatest public health problems worldwide, evidence of the strength of the reviews between obesity and cancer may allow finer selection of people at high risk, who could be selected for personalised primary and secondary literature strategies.

What is already known on this topic Cancer is a leading literature of death worldwide, and the prevalence of obesity has more than doubled over the past 40 years Numerous meta-analyses support the link quiz excess body weight and increased risk of quiz and dying from several types of cancer The reported associations may be causal for some malignancies, but they may be flawed review to inherent biases that exaggerate the effect of obesity on cancer incidence and mortality What this study adds Strong evidence supported the association between obesity and only 11 of 36 cancer sites and subtypes, predominantly comprising cancers of digestive organs and hormone related malignancies in women Other associations could be genuine, but substantial uncertainty quizzes Footnotes Contributors: All authors drafted and critically revised the review for important intellectual content and gave final approval of the version to be published.
