Introduction. The brand new top-lbs variation index (HWDI) try a new sign to possess contrasting carrying excess fat updates. When you are looks-lbs percentage (BF%) is considered to be by far the most specific being obese review product, it’s a more pricey method and a lot more difficult to measure than the others. Mission. Our very own objectives were to discover relationships between HWDI and you can BF% and also to find an effective BF% forecast model regarding HWDI when considering decades and you may intercourse. Approach. Bioelectrical impedance study was applied determine BF% in two,771 match adult Thais. HWDI is actually calculated once the difference between level and lbs. Pearson’s correlation coefficient was applied to evaluate the partnership anywhere between HWDI and you may http://www.datingranking.net/fr/sites-de-rencontre-pour-animaux-de-compagnie/ BF%. Numerous linear and you can nonlinear regression research were utilized to create the fresh BF% prediction design. Abilities. HWDI and you may BF% were found to be inverse hence connected with a tendency towards the a linear relationship. Outcome of a great multivariate linear regression analysis, which included HWDI and you will decades since the variables in the design, predicted BF% as ? 0.159 (HWDI) + 0.161 (age) for males and ? 0.265 (HWDI) + 0.132 (age) for ladies. Conclusions. Brand new anticipate model provides a straightforward-to-explore being obese evaluation tool that should let awareness of underweight and you will carrying excess fat requirements.
step one. Addition
Being obese is a type of disease in lot of places and has now much more end up being an international crisis resulting in straight down total well being all of the around the globe. From inside the 2014, the country Health Team (WHO) stated that regarding the 13%, or one in 10, of the globe inhabitants old more than 18 (11% people and you can fifteen% women) endured obesity . This dilemma is in charge of an increase in the fresh mortality price away from persistent situation (44% of diabetic issues, 23% out of heart disease, and you will seven% out of disease) [2, 3]. Throughout the Far-eastern community, Thailand positions 2nd large about Malaysia toward quantity of overweight some body. The main concern is the brand new apparent increase in the amount of youngsters having being obese. A study in 2010 said one in 10 people old ranging from 1 and you will 14 inside Thailand suffered from obesity .
Currently, you will find several popular solutions to assess overweightness and you will obesity in people. Body-fat percentage (BF%) is a precise and you will credible measurement means but is seemingly expensive and hard to utilize [5–9]. Dual-energy X-beam absorptiometry (DEXA) is considered as probably one of the most real actions together with standard on dimensions away from BF%. But not, this method is too high priced to possess typical have fun with, particularly in a source limited nation like Thailand, while bioelectrical impedance analysis (BIA) is actually more affordable plus fundamental and contains been proven to help you become sparingly exact when compared to the standard approach [10, 11].
Your body size index (BMI) is among the most prominent directory getting assessing lbs status that’s calculated out-of weight (kg) and you may top (yards 2 ) . However, this method demands extra equipment for aspect. Also, Body mass index can not be accustomed differentiate between a heavy otherwise heavy individual when a team contains a populace having typical bodyweight but highest BF%. This may result in a keen underestimation of amount of people during the a people with being obese . To conquer it restriction, the analysis Institute getting Health Sciences during the Thailand developed a simple directory getting tests overweightness and being obese called the level-pounds distinction index (HWDI) because of the determining the essential difference between height (cm) and pounds (kg). Nonetheless they discovered that HWDI is actually in the determining carrying excess fat incidence in the decades over 18 .
Relationship ranging from Level-Pounds Change Directory and the entire body-Fat Fee Estimated from the Bioelectrical Impedance Data into the Thai People
However, there was basically earlier in the day education which have examined the partnership anywhere between Body mass index and you may BF% [13, fifteen, 16], none had been located to have worried about the connection between HWDI and you can BF%. Our very own objectives were to get the dating anywhere between HWDI and BF% also to look for a good BF% prediction design to own being obese review.
