Summary This study explored the association of socioeconomic status with individuals’ perception of their body image (BI) and body weight (BW) among adults in a sub-urban Nigerian population. The cross-sectional sample comprised 1521 residents (775 males and 746 females) of the town of Nnewi. Perceived BI was assessed using figural representations of different sizes for males and females. Perceived BW was determined by presenting participants with BW category options to choose from. Body mass index (BMI) was calculated from objectively measured BW and height using standardized procedures. Actual BW categories were derived from participants’ BMIs using WHO criteria. Perceived BI and BW differed from actual BW among unskilled and non-tertiary males (p<0.001) and female (p<0.001 to p<0.04) in all BW categories whereas these variables differed (p<0.001) among skilled and tertiary males and females in normal weight, overweight and obese categories. Perceived BW differed (p<0.001) from actual BW among unskilled and non-tertiary males in underweight, overweight and obese categories whereas these variables differed (p<0.001) among unskilled and non-tertiary females, skilled and tertiary males and females in overweight and obese categories. Underweight 'unskilled' and 'non-tertiary' males perceived their BI to be different from their actual BW (p<0.001). Overweight and obese 'skilled' and 'unskilled', and 'tertiary' and 'non-tertiary', males and females perceived their BI and BW to be different from their actual BW (p<0.001). Significant differences in perceived BI existed between 'skilled' and 'unskilled' (p<0.001), and 'tertiary' and 'non-tertiary' (p=0.005), overweight males, and between 'skilled' and 'unskilled' (p<0.001), and 'tertiary' and 'non-tertiary' (p=0.008), normal-weight females. The 'skilled' participants had a lower risk of perceiving a larger BI (OR 0.51, 95% CI 0.41-0.64; p<0.001) and larger BW (OR 0.71, 95% CI 0.53-0.96; p=0.03) than the 'unskilled' participants. The 'tertiary' participants had a lower risk of perceiving a larger BI (OR 0.51, 95% CI 0.40-0.63; p<0.001) and larger BW (OR 0.71, 95% CI 0.53-0.95; p=0.02) than the 'non-tertiary' participants. After adjusting for possible confounders, all the risks became insignificant except for perception of BI by the 'skilled' participants (OR 0.70, 95% CI 0.50-0.99; p=0.04). Individuals in the different occupational and educational categories perceived their BI differently but their BW similarly. Given the same BMI, age, perceived ideal BI and sex, only occupation is found to be associated with perception of BI. HubMed – rehab

OBJECTIVE: To investigate whether an exercise program, initially focusing on knee stabilization and subsequently on muscle strength and performance of daily activities is more effective than an exercise program focusing on muscle strength and performance of daily activities only, in reducing activity limitations in patients with knee osteoarthritis (OA) and instability of the knee joint. DESIGN: A single-blind, randomized, controlled trial involving 159 knee OA patients with self-reported and/or biomechanically assessed knee instability, randomly assigned to two treatment groups. Both groups received a supervised exercise program for 12 weeks, consisting of muscle strengthening exercises and training of daily activities, but only in the experimental group specific knee joint stabilization training was provided. Outcome measures included activity limitations (WOMAC physical function, primary outcome), pain, global perceived effect and knee stability. RESULTS: Both treatment groups demonstrated large (?20-40%) and clinically relevant reductions in activity limitations, pain and knee instability, which were sustained six months post treatment. No differences in effectiveness between experimental and control treatment were found on WOMAC physical function (B (95% CI) = -0.01 (-2.58-2.57)) or secondary outcome measures, except for a higher global perceived effect in the experimental group (p=.04). CONCLUSIONS: Both exercise programs were highly effective in reducing activity limitations and pain and restoring knee stability in knee OA patients with instability of the knee. In knee OA patients suffering from knee instability, specific knee joint stabilization training, in addition to muscle strengthening and functional exercises, does not seem to have any additional value.

The objective of this study was to evaluate the Barrow Neurological Institute Screen for Higher Cerebral Functions (BNIS) in screening for cognitive dysfunction at long-term follow-up after stroke in young and middle-aged patients. Within the Sahlgrenska Academy Study on Ischemic Stroke Outcome, the BNIS and the Mini-Mental State Examination (MMSE) were administered to 295 consecutive surviving patients seven years after ischemic stroke. All participants were less than 70 years at index stroke. BNIS score less than 47 and an MMSE score less than 29 were chosen to indicate cognitive dysfunction. Two hundred eighty-one (95%) patients completed both tests. The 2 test scores were moderately correlated, and both tests correlated to disability as measured by the modified Rankin Scale. The distribution of the MMSE score was skewed toward the top scores, with a marked ceiling effect, whereas the BNIS score was more normally distributed. Most BNIS subscales showed mean performance around the mid of the scale without ceiling effects. Both tests identified a large proportion of the subjects as cognitive impaired, however, with a substantially larger proportion for the BNIS (89%) compared with the MMSE (65%). We conclude that the BNIS may be a useful screening instrument for cognitive dysfunction after ischemic stroke and that a large proportion of young and middle-aged ischemic stroke survivors showed signs of cognitive dysfunction long after index stroke. Further validations of BNIS against formal neuropsychological testing and studies of the determinants and consequences of long-term cognitive outcome in this patient group are warranted.
