Background & aims: Sarcopenic obesity may be defined by a high fat to fat-free mass (FM/FFM) ratio. Skeletal muscle may be negatively influenced by the pro-inflammatory milieu associated with visceral fat, while the loading effect induced by a heavier body mass index (BMI) may enhance muscle anabolism. Recently, a new anthropometric measure based on waist circumference (A Body Shape Index, ABSI) was developed. In this study we have assessed the predictive power of ABSI on the FFM index (FFMI), a surrogate marker of lean mass. Methods: Standard anthropometric parameters and ABSI as well as body composition data (fat and fat-free mass determined by bioelectrical impedance analysis) were assessed in 111 female and 89 male overweight/obese subjects, with no clinically significant co-morbidities. Groups with higher- or lower-ABSI were identified according to median values of this index. Results: In women and men, ABSI did not correlate with BMI, while multiple linear regression indicated that BMI (β-coefficients: 0.62 and 0.77, respectively) and ABSI (β-coefficients:-0.26 and-0.22, respectively) independently predicted FFMI (multiple R: 0.72 and 0.83, respectively, P<0.001). Men and women with lower-ABSI exhibited significantly greater FFMI than the higher-ABSI groups for comparable values of BMI. In men, ABSI was correlated positively with C-reactive protein (CRP) (R=0.30; P<0.05) and negatively with the reciprocal of insulin (R=0.28; P<0.05), an index of insulin sensitivity. FM/FFM ratio significantly (P<0.01) correlated with CRP (R=0.31) in women only. Conclusions: ABSI, a recently introduced marker of abdominal adiposity, may contribute to define the risk of sarcopenia in overweight/obese individuals. © 2014.

The increasing need for nutrition professionals is driven by growing public interest in nutrition and the potential of nutrition to prevent and treat a variety of diet-related conditions. Health promotion units and health services face great challenges in trying to address current and future population health issues. This review describes the present state of health nutrition practice in Italy, exploring the nature, role, and utility of training for nutrition professionals to meet the increasing burden of nutrition-related diseases. Evidence suggests that the public health nutrition workforce and infrastructures lack the necessary capacity to respond to national population needs regarding food and nutrition at many levels. This situation is aggravated by the growing prevalence of nutrition-related diseases as well as by the lack of adequate academic nutrition training. The public health nutrition infrastructures need to be enhanced, as do the education and training systems. Roles and functions in health nutrition practice need to be defined and discipline-specific competencies should be integrated. © 2010 International Life Sciences Institute.
