Abstract:

Personal assessments of body phenotype can enhance success in weight management but are limited by the lack of availability of practical methods. We describe a novel smart phone application of digital photography (DP) and determine its validity to estimate fat mass (FM).
This approach utilizes the percent (%) occupancy of an individual lateral whole-body digital image and regions indicative of adipose accumulation associated with increased risk of cardio-metabolic disease. We measured 117 healthy adults (63 females and 54 males aged 19 to 65 years) with DP and dual X-ray absorptiometry (DXA) and report here the development and validation of this application.
Inter-observer variability of the determination of % occupancy was 0.02%. Predicted and reference FM values were significantly related in females (R2 = 0.949, SEE = 2.83) and males (R2 = 0.907, SEE = 2.71).
Differences between predicted and measured FM values were small (0.02 kg, p = 0.96 and 0.07 kg, p = 0.96) for females and males, respectively. No significant bias was found; limits of agreement ranged from 5.6 to 5.4 kg for females and from 5.6 to 5.7 kg for males. These promising results indicate that DP is a practical and valid method for personal body composition assessments.

Abstract:
The need for a practical method for routine determination of body fat has progressed from body mass index (BMI) to bioelectrical impedance analysis (BIA) and smartphone two-dimensional imaging. We determined agreement in fat mass (FM) estimated with 50 kHz BIA and smartphone single lateral standing digital image (SLSDI) compared to dual X-ray absorptiometry (DXA) in 188 healthy adults (69 females and 119 males). BIA underestimated (p < 0.0001) FM, whereas SLSDI FM estimates were not different from DXA values. Based on limited observations that BIA overestimated fat-free mass (FFM) in obese adults, we tested the hypothesis that expansion of the extracellular water (ECW), expressed as ECW to intracellular water (ECW/ICW), results in underestimation of BIA-dependent FM. Using a general criterion of BMI > 25 kg/m2, 54 male rugby players, compared to 40 male non-rugby players, had greater (p < 0.001) BMI and FFM but less (p < 0.001) FM and ECW/ICW. BIA underestimated (p < 0.001) FM in the non-rugby men, but SLSDI and DXA FM estimates were not different in both groups. This finding is consistent with the expansion of ECW in individuals with excess body fat due to increased adipose tissue mass and its water content. Unlike SLSDI, 50 kHz BIA predictions of FM are affected by an increased ECW/ICW associated with greater adipose tissue. These findings demonstrate the validity, practicality, and convenience of smartphone SLSDI to estimate FM, seemingly not influenced by variable hydration states, for healthcare providers in clinical and field settings.

Abstract: Limitations of body mass index (BMI) as a measure of body fat and the need for practical methods to estimate body fat reinforce interest in smartphone two-dimensional digital imaging and bioelectrical impedance analysis (BIA). Compared to dual x-ray absorptiometry (DXA), we determined differences in body fat mass (FM) estimated with smartphone single lateral standing digital image (SLSDI) and bioimpedance analysis (BIA) in 188 healthy adults (69 females and 119 males). SLSDI FM estimates were similar to DXA values but BIA underestimated (p<0.0001) FM. We tested the hypothesis that fluid imbalance, expansion of the extracellular water (ECW), designated as ECW to intracellular water ratio (ECW/ICW), affects the BIAdependent differences. With BMI>25 kg/m2, 54 male rugby players, compared to 40 male non-rugby players, had greater (p<0.001) BMI and fat-free mass but less (p<0.001) FM and ECW/ICW. SLSDI and DXA FM estimates were not different in both groups; BIA underestimated (p<0.001) FM in the non-rugby men. This finding is consistent with expansion of ECW in individuals with excess body fat due to increased adipose tissue mass and its water content. Unlike SLSDI, BIA predictions of FM are affected by altered fluid distribution associated with increased adipose tissue. These findings establish the validity, practicality, and convenience of smartphone SLSDI to estimate FM for healthcare providers in clinical and field settings.



Is Digital Image Plethysmographic (DIP) Acquisition a Valid New Tool for Preoperative Body Composition Assessment? A Validation by Dual-energy X-ray Absorptiometry (2006)

Abstract

BACKGROUND:
The increasing incidence of obesity and the wider acceptance of laparoscopic surgery, have lead to a 10-fold increase in bariatric operations in the last 10 years. Widely used indices of obesity (weight and body mass index – BMI) cannot adequately distinguish between fat mass (FM), represented by the sum of kilograms (kg) of lipid, and fat-free mass (FFM), inclusive of lean (kg of proteins), bone (kg of minerals), glycogen, and total body water (TBW), which are important parameters for clinical and physiological studies.

METHODS:
Anthropometric variables were measured in 19 Caucasian Italian individuals according to standard methods. Body weight (kg) and height (m) were measured, and BMI was calculated as kg/m(2). Body composition was evaluated, with a mean BMI of 25.95+/-5.04 kg/m(2), by dual X-ray absorptiometry (DXA) and by digital image plethysmographic (DIP) acquisition with a digital camera. The clear-colored body of the subjects was automatically converted into a front and lateral red-shaped figure, and then through algorithms the 2 pictures were transformed into a nominal volume; body weight was then divided by the estimated volume, so that the body density could be obtained. DXA was used as a comparison to assess fat mass and fat-free mass. Radiation exposure was <0.6 mSv.

RESULTS:
Significant positive correlation (R= 0.971, P<0.001) was found between data of body composition obtained by DXA and DIP.
CONCLUSIONS:
Body volume assessed using DIP or DXA did not differ. According to this validation study, DIP represents a new promising tool for clinical applications.



A new simplified method for tracking body volume changes using digital image plethysmography (DiP) (2008)

Jordan R. Moon, Sarah E. Tobkin – Ashley A. Walter – Abbie E. Smith – Chris M. Lockwood – Travis W. Beck – Joel T. Cramer – Jeffrey R. Stout,

OBJECTIVE:
Tracking body composition changes during weight-loss interventions is important in both clinical and commercial settings. Accurately tracking body volume (BV) changes can be a useful method to examineweight-loss interventions because BV is not dependent on age, ethnicity, sex,oractivity level. However, measuring BV using air-displacement plethysmography (ADP) or hydrostatic weighing (HW) is expensive, time-consuming, and requires skilled technicians. Therefore, the purpose of the current investigation was to examinethe validity of digital image plethysmography (DiP) for estimating BV before and after a 10-week weight-loss intervention.

METHODS:
Twenty-two men(M)and women(W)(33±6yr; 12M, 10W) volunteered to have their BV estimated by ADP and DiP measurements. Thirteen subjects (8M, 5W) participated in a10-week exercise program (EX) while 9 subjects maintained their current activity level (CON). The following previously validated DiP equation(versus HW, r2=0.99, total error (TE) =1.54L,  SEM=0.85L)was used to track changes using the DiP method: BV=0.0011(side body pixels) +2.08415 (total body pixels to empty pixel space percentage) -69.29694.


RESULTS: Preand Post TE values for both groups were less than 2.55L with high r2 and low SEEvalues (EX r2>0.97, SEE<1.72L; CON r2>0.98, SEE<1.94L). DiP accurately estimated BV changes (EX TE=1.06 L, SEE=1.00 L; CON TE=0.83 L, SEE=0.47 L) which were not significantly different (constant error, EX=-0.53, CON=0.33p>0.05) compared to ADP.
CONCLUSION:
The new DiP-based BV equation produced low SEE and TE values andhigh r2 values in both the EX and CON groups and accurately tracked BV changes. Therefore, DiP can be considered a valid method for estimatingand tracking BV in men and women.
