Background: Obesity increases the risk of many cancers including colorectal cancer (CRC).
Methods: This is secondary data analysis of the 2010 National Health Interview Survey data. A total of 9360 obese and overweight participants, aged 50 to 80 years, were analyzed according to their perception of their personal cancer risk.
Results: Having a perception of increased risk for cancer was associated with higher CRC screening rates. However, when compared with their normal-weight counterparts, overweight and obese individuals did not perceive themselves as being at an increased risk for cancer in general or for CRC specifically. Subgroup analysis revealed one notable exception. Obese black women appeared to recognize themselves as being at higher risk for CRC.
Conclusions: Most obese and overweight individuals fail to recognize their increased cancer risk. Individuals who perceive themselves as being at increased risk for cancer, especially CRC, are more likely to have undergone CRC screening. Unfortunately, obese and overweight individuals do not seem to recognize the increased cancer risk conferred by their body weight. Education is needed so that obese and overweight individuals are aware that their excess body weight is a risk factor for cancer.

Background Context: There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor).

Research Question: Does endometrial preparation using a natural cycle lead to higher live birth rates (LBR) in single euploid frozen embryo transfers (FET) compared with programmed cycles, for women who are normal weight, overweight and obese.
Design: Retrospective study of 845 single euploid FETs from 688 couples. Patients were stratified by body mass index (BMI) into normal weight, overweight and obesity class I/II categories.

Background And Aim: A healthy diet has been recommended for non-alcoholic fatty liver disease (NAFLD). We aim to investigate the associations of diet quality indices with the risk of developingmetabolic-associated fatty liver disease (MAFLD).
Methods: We conducted this nested case-control study by recruiting 968 cases with MAFLD and 964 controls from the participants of the baseline phase of the Sabzevar Persian Cohort Study (SPCS).

It is well recognized that type II Diabetes (T2D) and overweight/obesity are established risk factors for stroke, worsening also their consequences. However, the underlying mechanisms by which these disorders aggravate outcomes are not yet clear limiting the therapeutic opportunities. To fill this gap, we characterized, for the first time, the effects of T2D and obesity on the brain repair mechanisms occurring 7 days after stroke, notably glial scarring.
