The most common methods of assessing degree of obesity in humans are reviewed. These include anthropometry, somatotyping, bodyweight, skinfold calipering, densitometry, and several nondensitometric procedures. The evidence suggests that bodyweight may often be an unreliable and invalid index of obesity. The parameters influencing its inaccuracy are discussed. These include age, height, sex, muscularity, and degree of obesity or amount of recent weight loss. The most reliable and valid measures of human bodyfat are generally the most complicated and impractical. Compromise assessment procedures involving nonintrusive measurement of subcutaneous fat and selected anthropometric dimensions may offer an incomplete but welcome improvement over sole reliance on bodyweight as an index of obesity.  相似文献

Knowledge and understanding about the impact of cumulative adverse experiences on the health and wellbeing of children, adolescents, and adults has rapidly expanded over the past 30 years. Despite the invaluable attention and support this proliferation has drawn to the importance of early childhood experiences, we believe that it is time to move beyond broad indices of risk and toward more specific and individualized understanding of how risk exposures are linked to clinical outcomes in young children. Within infant and early childhood mental health, there is a need for greater specificity in linking adverse caregiving experiences in early life to psychopathology in children. We highlight a framework distinguishing experiences of trauma from experiences of deprivation and use the examples of posttraumatic stress disorder and reactive attachment disorder to demonstrate how greater specificity in our understanding of early adverse caregiving can lead to more accurate and targeted diagnosis and treatment for young children. Both researchers and clinicians benefit from an approach to gain a greater appreciation of the links between specific types of experiences and outcomes in the children that we serve.  相似文献

Wearing costumes is a common experience during early childhood and is often important to sociodramatic play. Costumes tend to be highly gendered for both girls and boys (such as princess and superhero costumes). However, there is very little research on the impact that wearing costumes has on gender-differentiated behavior, such as toy preference, prosocial behavior, or perseverance during early childhood. The current study included 223 U.S. children, aged between 3 and 5 years-old. Children were assigned to wear either a gendered, counter-gendered, or gender-neutral costume, and they then took part in three gender-related tasks. There was no impact of wearing costumes on any task for girls. However, boys preferred feminine toys significantly more when wearing a neutral costume when compared to a masculine-typed one. Additionally, boys were significantly less likely to help when wearing a masculine-typed costume compared to a feminine-typed costume. There are several implications of these findings that are discussed in the paper. Parents may wish to purchase a wide range of costumes for their child for sociodramatic play, particularly for boys. Therapists could also potentially use costumes during play therapy to discuss gender issues. Additionally, costume producers could consider marketing a wide range of costumes for children as opposed to largely focusing on gendered ones.
