ABSTRACT
BACKGROUND: Patients with insulin-treated diabetes struggle with performing accurate carbohydrate counting for proper blood glucose control. Little is known about the comparative accuracy and feasibility of carbohydrate counting methods. PURPOSE: The purpose of this study was to determine whether carbohydrate counting using a smartphone application is more accurate and feasible than a traditional method. THEORETICAL/CONCEPTUAL FRAMEWORK: Based on a conceptual model derived from the Technology Acceptance Model, feasibility was defined as usefulness, ease of use, and behavioral intention to use each method. METHODS: A standardized meal was presented to 20 adults with insulin-treated diabetes who counted carbohydrates using traditional and smartphone methods. Accuracy was measured by comparing carbohydrate counting estimates with the standardized meal values. Perceived feasibility (usefulness, ease of use, behavioral intention) was measured using rating forms derived from the Technology Acceptance Model. RESULTS: The number of training and estimation minutes were significantly higher for the traditional method than the smartphone method (Z = -3.83, P < .05; Z = -2.30, P < .05). The traditional method took an additional 1.4 minutes for estimation and 12.5 minutes for training. There were no significant differences in accuracy between traditional and smartphone methods for carbohydrate counting (Wilcoxon signed-rank test, Z = -1.10, P = .28). There were no significant differences between traditional and smartphone methods for feasibility (usefulness, Z = -.10, P = .95; ease of use, Z = -.36, P = .72; or behavioral intention, Z = -.94, P = .35). CONCLUSION: While both traditional and smartphone methods were found to be similar in terms of accuracy and feasibility, the smartphone method took less time for training and for carbohydrate estimation.
ABSTRACT
Background: One way to address substance misuse is to train health professional students in Screening, Brief Intervention, and Referral to Treatment (SBIRT), an early intervention strategy. This study evaluated a semester-long, 50-hour elective SBIRT training that blended online coursework with interprofessional experiences. Medicine, nursing, pharmacy, and social work students completed an interprofessional standardized patient experience and completed a minimum of two interprofessional SBIRT experiences at community agencies. Methods: We analyzed longitudinal data from 197 students using structural equation modeling to examine gains in knowledge and perceived competence, as well as to test if background variables predicted 30-day application of SBIRT knowledge and skills, 30-day satisfaction' 12-month frequencies of care for performing SBIRT; and number of SBIRT clients/patients served directly. Results: Overall, student SBIRT knowledge and perceived competence both increased by more than a standard deviation during the course. Students who experienced larger gains in perceived competence rated the course significantly higher in terms of relevance and usefulness and, in turn, served significantly more SBIRT clients/patients during the following year. We did not find evidence that intra-individual growth in knowledge impacted the degree to which students ultimately applied SBIRT components. Finally, students who had more previous training and experience related to substance abuse ultimately reported greater application of SBIRT knowledge and skills. Interprofessional differences included: At baseline, medicine students had significantly lower substance abuse education knowledge as compared to the other disciplines. Pharmacy and social work students were more likely to have had previous experience with motivational interviewing. Baseline perceived competence in applying SBIRT was higher in social work and nursing. Upon completion, pharmacy and medicine students had lower satisfaction with the course. Conclusions: These findings suggest that SBIRT courses can increase knowledge and perceived competence; moreover, student background characteristics, work settings, and experiences may have important effects on learning SBIRT.

Family caregivers exhibit a wide variety of needs and concerns while providing care to stroke survivors after discharge to the home setting. We report the results of two related studies utilizing a multimethod design in which stroke family caregivers (N = 12; N = 10) were interviewed using open-ended questions, followed by written caregiver ratings regarding the types of telehealth technologies they preferred for the telephone assessment and skill-building kit (TASK III). Qualitative data were analyzed using content analysis procedures with a provisional "start list" of codes in a matrix template based on the types of telehealth technologies in the rating forms. Descriptive statistics were used to analyze ratings with response scales ranging from 1 = strongly disagree to 5 = strongly agree. Average ratings for the telehealth technologies for the TASK III resource guide were obtained for the mailed hard copy binder (M = 3.58-4.13; SD = 0.35-1.00), an interactive website (https://www.task3web.com/; M = 3.86-4.17; SD = .72-1.07), an eBook (M = 3.17-3.67; SD = 0.84-1.17), and a USB drive (M = 3.75-4.00; SD = .82-.96). Average ratings for the telehealth technologies for the TASK III calls with the nurse were obtained for the use of a telephone (M = 4.36-5.00; SD = 0.00-0.89), FaceTime on an iOS device (e.g., iPhone or iPad; M = 3.73-4.40; SD = 0.79-0.98), or online videoconferencing (M = 3.17-3.50; SD = 0.82-1.47). Qualitative data revealed a wide variety of preferences for each type of telehealth technology, with advantages and disadvantages of each. The findings underscored the importance of offering multiple telehealth technology options to stroke family caregivers. Future studies are recommended that employ randomized control trial methodology to test theoretically-based interventions that are based on stroke family caregiver preferences for telehealth technologies.

BACKGROUND: Few studies have addressed the effect of bariatric surgery on factors related to energy balance, including resting energy expenditure (REE) and thermic effect of food (TEF). To our knowledge, very few studies have examined changes in REE and none have investigated modifications in TEF after sleeve gastrectomy (SG) performed in adolescents. OBJECTIVE: To assess energy expenditure in females who underwent SG as adolescents and matched-control participants as preliminary data about the potential of SG to confer differences in postprandial energy expenditure. SETTING: Children's Hospital Medical Center, Cincinnati, Ohio, United States. METHODS: In this observational study, REE and respiratory quotient (RQ) were measured via indirect calorimetry, followed by a standardized meal and assessment of TEF and postprandial RQ. Plasma drawn before and every 15 minutes after the meal was assayed for insulin, glucose, and C-peptide. Usual dietary intake was estimated using 24-hour recall interviews. RESULTS: Fasting REE and RQ were similar between surgical and control groups. Postmeal TEF also did not differ between groups. The surgical group had higher RQ early in the postprandial period, whereas the control group RQ was higher after 125 minutes post meal. Compared with the control group, the surgical group had lower postprandial glucose, higher insulin and C-peptide, and consumed less daily energy during usual intake. CONCLUSIONS: Postprandial RQ was consistent with the rapid gastric emptying typical of SG, yet we observed no group differences in REE or TEF. These findings may have been due to limited statistical power. More comprehensive studies of EE after SG are warranted.

OBJECTIVE: This study's objective was to determine whether two distinct carbohydrate (CHO)-modified diets and a standard portion-controlled (PC) diet differentially impacted children's eating behaviors and whether eating behavior scores predicted lower BMI among children with obesity. METHODS: Children (n = 102) aged 7-12 years with obesity were randomly assigned to a 12-month intervention of a low-carbohydrate (LC), reduced glycemic load (RGL), or standard PC diet. The Three-Factor Eating Questionnaire (TFEQ) was completed at baseline, 3, 6, and 12 months by parents to characterize their child's hunger (H), disinhibition (D), and cognitive restraint (CR). Baseline and follow-up TFEQ scores by diet were evaluated relative to BMI status over time. RESULTS: All diet groups showed increased CR and decreased H and D from baseline to 3 months, with differences from baseline remaining at 12 months for CR and H. Lower BMI status during study follow-up was associated with different TFEQ scores by diet group (LC and RGL: higher CR; PC: lower H), adjusting for sex, age, and race. Higher CR at follow-up was predicted by race and higher baseline CR; only lower H at baseline predicted lower H at follow-up. CONCLUSION: Eating behaviors improved significantly with all diets during the initial 3 months; higher CR and lower H were sustained at treatment's end. BMI outcomes were associated with different eating behaviors in CHO-modified diet groups compared with PC diets. Targeting diets of children with obesity with specific baseline characteristics may lead to improved outcomes.

OBJECTIVE: To compare the effectiveness and safety of carbohydrate (CHO)-modified diets with a standard portion-controlled (PC) diet in obese children. STUDY DESIGN: Obese children (n=102) aged 7-12 years were randomly assigned to a 3-month intervention of a low-CHO (LC), reduced glycemic load (RGL), or standard PC diet, along with weekly dietary counseling and biweekly group exercise. Anthropometry, dietary adherence, and clinical measures were evaluated at baseline and 3, 6, and 12 months. Analyses applied intention-to-treat longitudinal mixed models. RESULTS: Eighty-five children (83%) completed the 12-month assessment. Daily caloric intake decreased from baseline to all time points for all diet groups (P<.0001), although LC diet adherence was persistently lower (P<.0002). At 3 months, body mass index z score was lower in all diet groups (LC, -0.27 ± 0.04; RGL, -0.20 ± 0.04; PC, -0.21 ± 0.04; P<.0001) and was maintained at 6 months, with similar results for waist circumference and percent body fat. At 12 months, participants in all diet groups had lower body mass index z scores than at baseline (LC, -0.21 ± 0.04; RGL, -0.28 ± 0.04; PC, -0.31 ± 0.04; P<.0001), and lower percent body fat, but no reductions in waist circumference were maintained. All diets demonstrated some improved clinical measures. CONCLUSION: Diets with modified CHO intake were as effective as a PC diet for weight management in obese children. However, the lower adherence to the LC diet suggests that this regimen is more difficult for children to follow, particularly in the long term.

PURPOSE: To determine the effects of an environmental intervention on obesity, disease risk factors, and dietary intake in an employee population. DESIGN: Randomized controlled community trial. SETTING: Eight manufacturing companies in Kentucky with â¼150 to 350 employees each. SUBJECTS: Randomly selected employees. INTERVENTION: Multicomponent environmental intervention that included employee advisory committees, point-of-decision prompts, walking paths, cafeteria/vending changes, and educational materials. MEASURES: Height; weight; body fat; blood pressure; fasting lipids, glucose and insulin; and dietary intake were assessed prior to and 3, 6, and 12 months after initiation of the intervention. ANALYSIS: Mixed-model repeat-measure analyses of covariance were used to analyze data collected over the study period. Categorical data were analyzed in contingency tables. A p value of .05 was used to judge statistical significance. RESULTS: There were no intervention effects for outcome variables, with the exception of lower intake of saturated fat and dietary cholesterol in the intervention group compared to the control group. Over the course of the study, changes in anthropometry and biomeasures were similar in both groups. CONCLUSIONS: Findings indicate that subtle environmental changes alone may not impact employees' weight and health; however, such institutional-level approaches may be essential to support healthy lifestyle habits that are initiated by more intensive efforts. Academic researchers should continue to partner with employers and practitioners to develop, implement, and evaluate innovative health promotion strategies including environmental interventions.

Adiponectin is an adipose-derived protein with beneficial metabolic effects. Low adiponectin is associated with obesity and related diseases. Significant weight loss increases adiponectin, reducing disease risk. This study compared the effects of two weight-loss diets with different macronutrient compositions on adiponectin. Eighty-one obese women in two cohorts were randomized to a low-fat (LF) or a low-carbohydrate (LC) diet. All subjects underwent equivalent weight-loss intervention, with weight and other measures assessed at baseline and after 6 (cohort I) or 4 (cohort II) months. Body fat was measured by dual energy X-ray absorptiometry. Adiponectin was measured by radioimmunoassay. Diet intake was assessed using 24-h recalls and 3-day diet records. Data were analyzed via t-tests and repeated-measures factorial ANOVA using time, diet, and replicate (cohort I vs. cohort II) as factors. Age, weight, body fat, BMI, adiponectin, and diet were similar at baseline. Following intervention, macronutrient composition of the diet was vastly different between the groups, reflecting the assigned diet. Both groups lost weight and body fat (P < 0.001), with effect in LC dieters greater than LF dieters (-9.1 kg vs. -4.97 kg weight, P < 0.05 and -5.45 kg vs. -2.62 kg fat, P < 0.001). Adiponectin increased in the LC (+1.92 mcg/ml, P < 0.01), but not the LF (+0.86 mcg/ml, P = 0.81), group. There was no correlation between weight loss and increase in adiponectin. These results confirm that diet-induced loss of weight and body fat is associated with increased adiponectin concentrations. This effect is evident with weight loss of 10% or more, and may be greater with LC diets.

It is estimated that American employers spend more than $900 billion annually on health care and that obesity-attributable health care expenditures total $75 billion. The authors discuss a yearlong health promotion research project aimed at obesity and involving eight small manufacturing companies. Three hundred forty-one employees randomly selected at the intervention and control worksites were followed at baseline and at 3, 6, and 12 months for anthropometric measures, lifestyle behaviors, absences, and work performance. The authors conclude that although the worksite offers unique opportunities to develop health promotion programs, these efforts are not without challenges due to the tensions regarding the need to protect and promote health for the population, the increasing concerns over health care costs and access, and the priority to maintain individuals' rights and privacy.

OBJECTIVE: The purpose of this study was to compare the effects of high-monounsaturated fatty acid (MUFA) and high-carbohydrate (CHO) diets on body weight and glycemic control in men and women with type 2 diabetes. RESEARCH DESIGN AND METHODS: Overweight/obese participants with type 2 diabetes (n = 124, age = 56.5 +/- 0.8 years, BMI = 35.9 +/- 0.3 kg/m2, and A1C = 7.3 +/- 0.1%) were randomly assigned to 1 year of a high-MUFA or high-CHO diet. Anthropometric and metabolic parameters were assessed at baseline and after 4, 8, and 12 months of dieting. RESULTS: Baseline characteristics were similar between the treatment groups. The overall retention rate for 1 year was 77% (69% for the high-MUFA group and 84% for the high-CHO group; P = 0.06). Based on food records, both groups had similar energy intake but a significant difference in MUFA intake. Both groups had similar weight loss over 1 year (-4.0 +/- 0.8 vs. -3.8 +/- 0.6 kg) and comparable improvement in body fat, waist circumference, diastolic blood pressure, HDL cholesterol, A1C, and fasting glucose and insulin. There were no differences in these parameters between the groups. A follow-up assessment of a subset of participants (n = 36) was conducted 18 months after completion of the 52-week diet. These participants maintained their weight loss and A1C during the follow-up period. CONCLUSIONS: In individuals with type 2 diabetes, high-MUFA diets are an alternative to conventional lower-fat, high-CHO diets with comparable beneficial effects on body weight, body composition, cardiovascular risk factors, and glycemic control.

PURPOSE OF REVIEW: High-protein diets, often with carbohydrate restriction, are quite popular among overweight Americans pursuing strategies for weight control. Recently, well designed clinical trials have evaluated the anthropometric and metabolic effects of these diets. This review focuses on the impact of high-protein diets on energy expenditure and satiety; the diets' effects on weight loss, body composition, cardiovascular risk, and glycemic control; and potential detrimental consequences of high-protein intake. RECENT FINDINGS: Current evidence indicates that protein-induced energy expenditure and satiety contribute to weight control. Randomized, controlled trials continue to show comparable, if not superior, effects of high-protein diets compared with lower protein diets on weight loss, preservation of lean body mass, and improvement in several cardiovascular risk factors for up to 12 months. Evidence that chronic high-protein intake affects glucose metabolism is inconclusive at present. Further study of the long-term safety of diets with varying amounts of protein is warranted. SUMMARY: On the basis of patients' metabolic profiles and preferences, practitioners can recommend individualized, nutrient-rich diets within current nutritional guidelines for weight control. Diets moderately increased in protein and modestly restricted in carbohydrate and fat, particularly saturated fat, may have beneficial effects on body weight, body composition, and associated metabolic parameters. Key issues must be resolved regarding the long-term compliance and safety of chronic high-protein intake.

Although circulating glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD), a minor high-density lipoprotein-associated protein, is elevated in patients with insulin resistance or high triglycerides, no information is available on the effect of weight loss or changes in insulin sensitivity on circulating GPI-PLD levels. The objective of the study was to determine the effect of weight loss and changes in insulin sensitivity on plasma GPI-PLD levels. Forty-two nondiabetic obese women were included in the study, which involved a 3-month dietary intervention randomizing patients to a low-fat or a low-carbohydrate diet. The study's main outcome measures were plasma GPI-PLD levels and insulin sensitivity as estimated by the homeostasis model assessment. The very low carbohydrate diet group lost more weight after 3 months (-7.6 +/- 3.2 vs -4.2 +/- 3.5 kg, P < .01), although the decrease in insulin resistance was similar between groups. Weight loss with either diet did not alter plasma GPI-PLD levels. However, baseline GPI-PLD levels correlated with the change in insulin sensitivity in response to the low-fat diet, whereas baseline insulin sensitivity correlated with the change in insulin sensitivity in response to the low-carbohydrate diet. Plasma GPI-PLD may serve as a clinical tool to determine the effect of a low-fat diet on insulin sensitivity.

OBJECTIVE: To examine whether obesity is associated with increased presenteeism (health-related limitations at work). METHODS: Randomly selected manufacturing employees (n = 341) were assessed via height and weight measures, demographic survey, wage data, and the Work Limitations Questionnaire. The Work Limitations Questionnaire measures productivity on four dimensions. Analyses of variance and analyses of covariance were computed to identify productivity differences based on body mass index (BMI). RESULTS: Moderately or extremely obese workers (BMI > or =35) experienced the greatest health-related work limitations, specifically regarding time needed to complete tasks and ability to perform physical job demands. These workers experienced a 4.2% health-related loss in productivity, 1.18% more than all other employees, which equates to an additional $506 annually in lost productivity per worker. CONCLUSIONS: The relationship between BMI and presenteeism is characterized by a threshold effect, where extremely or moderately obese workers are significantly less productive than mildly obese workers.

With the rising prevalence of both obesity and diabetes, the contributing role of diet to the prevention and treatment of these conditions has become a major focus of research, clinical practice, and public policy. There has been intense debate over which dietary regimens might be most effective for weight loss, with interest centered on the potential for specific dietary macronutrients to affect body composition, metabolism, and overall health. This Review addresses two regimens with distinct macronutrient prescriptions that have been widely touted as being beneficial for weight loss and/or metabolic profile: diets low in carbohydrate and diets high in monounsaturated fat. Although data from recent randomized, controlled trials suggest these popular diets may be useful for weight control, cardiovascular health, and glycemic control, longer studies of the efficacy and safety of varying macronutrient content are needed to strengthen the evidence base for nutritional recommendations. Until more support for specific macronutrient combinations is available, practitioners can recommend an array of diets with moderate amounts of macronutrients, tailored to individual needs and preferences.

Faculty from the Colleges of Nursing, Pharmacy, Social Work and Allied Health Sciences at the University of Cincinnati collaborated to create an elective course that focused on providing students the opportunity for interprofessional education (IPE) and cultural competence training. The course was designed around the educational principles described in the literature as most effective for IPE: interpersonal and small-group skills, face-to-face interaction, positive interdependence, individual accountability and group processing. Impact of the course was assessed using two questionnaires focusing on interdisciplinary interactions and cultural competence, respectively. The Student Attitude Questionnaire (SAQ) and Inventory for Assessing The Process of Cultural Competence Among Health Care Professionals-Revised (IAPCC-R) were administered to students prior to the start of the course and at the end of the course. The SAQ results indicated that students perceived the course to be beneficial in the following areas: interprofessional team work, professionalism, self-confidence, communication skills, and improved understanding of the roles of health professionals and the impact of each profession on patient care. The course also promoted students' progress on their personal and professional journeys toward cultural proficiency as noted by changes in their pre//post-course IAPCC-R scores. Students moved from being culturally aware to becoming culturally competent. The design and evaluation of this class can be used as a model by other universities to promote interdisciplinary team skills in health professions students and to provide additional opportunities for cultural competence training.

The purpose of this study was to examine the prevalence of obesity and cardiovascular risk factors among male and female employees of eight small manufacturing companies in Kentucky. Randomly selected employees were screened using anthropometric and metabolic measures and a food frequency questionnaire. More than 77% of participants were classified as overweight or obese, higher than national estimates. Obesity was associated with a higher prevalence of hypertension, dyslipidemia, and elevated fasting glucose. Consistent with national data, males had an increased prevalence of specific risk factors (i.e., elevated blood pressure, low high-density lipoprotein cholesterol, and hypertriglyceridemia), while females had an increased prevalence of at-risk waist circumference. One potential contributor to high prevalence rates was dietary practices that did not meet recommended guidelines for health. Results suggest an increased risk for cardiovascular disease among employees of Kentucky manufacturing companies and the need for interventions to reduce obesity and its comorbidities in this target population.

OBJECTIVE: To provide interdisciplinary structured activities in academic and clinical settings for introducing the concept of professionalism to health professions students. DESIGN: Undergraduate and graduate students from 8 health care disciplines including pharmacy, nursing, communication sciences and disorders, dietetics and nutrition science, genetic counseling, advanced medical imaging, medical technology, and physical therapy participated in an orientation program focusing on interdisciplinary health care and professionalism, as well as a field experience. ASSESSMENT: Survey results from both components (orientation, n = 284; field experience, n = 123) indicated that the project was valuable in increasing students' awareness of (1) the importance of professionalism in the clinical setting and (2) the potential contributions of their profession to the health care team. CONCLUSION: Health professions curricula should include interdisciplinary learning opportunities that enhance collaboration, collegiality, and professionalism among future members of the health care team.

It is estimated that employers spend more than 75 billion dollars annually on obesity-attributable health care. Interventions to reduce or prevent the risk of obesity are increasingly common at worksites and include health fairs, weight loss and nutrition classes, and fitness programs. However, many companies lack the resources to plan and implement these types of programs. Environmental approaches offer companies a low-cost option. A community-based participatory research model was used to bring academic researchers, human resources personnel, and health department educators together to plan and implement an environmental program aimed at increasing healthy eating and physical activity at four small manufacturing companies. The Diffusion of Innovations Theory guided the development of focus group questions. A focus group study was then conducted to gather information from employees and managers at these four companies. The questions identified workplace strategies that would aid in reducing barriers and developing appropriate communication channels to enhance employee participation in the program. The researchers identified themes from manager and employee focus groups regarding the following five environmental components: signs, walking paths, food changes, educational strategies, and advisory groups.

BACKGROUND: Low-carbohydrate diets have become increasingly popular for weight loss. However, evidence from individual trials about benefits and risks of these diets to achieve weight loss and modify cardiovascular risk factors is preliminary. METHODS: We used the Cochrane Collaboration search strategy to identify trials comparing the effects of low-carbohydrate diets without restriction of energy intake vs low-fat diets in individuals with a body mass index (calculated as weight in kilograms divided by the square of height in meters) of at least 25. Included trials had to report changes in body weight in intention-to-treat analysis and to have a follow-up of at least 6 months. Two reviewers independently assessed trial eligibility and quality of randomized controlled trials. RESULTS: Five trials including a total of 447 individuals fulfilled our inclusion criteria. After 6 months, individuals assigned to low-carbohydrate diets had lost more weight than individuals randomized to low-fat diets (weighted mean difference, -3.3 kg; 95% confidence interval [CI], -5.3 to -1.4 kg). This difference was no longer obvious after 12 months (weighted mean difference, -1.0 kg; 95% CI, -3.5 to 1.5 kg). There were no differences in blood pressure. Triglyceride and high-density lipoprotein cholesterol values changed more favorably in individuals assigned to low-carbohydrate diets (after 6 months, for triglycerides, weighted mean difference, -22.1 mg/dL [-0.25 mmol/L]; 95% CI, -38.1 to -5.3 mg/dL [-0.43 to -0.06 mmol/L]; and for high-density lipoprotein cholesterol, weighted mean difference, 4.6 mg/dL [0.12 mmol/L]; 95% CI, 1.5-8.1 mg/dL [0.04-0.21 mmol/L]), but total cholesterol and low-density lipoprotein cholesterol values changed more favorably in individuals assigned to low-fat diets (weighted mean difference in low-density lipoprotein cholesterol after 6 months, 5.4 mg/dL [0.14 mmol/L]; 95% CI, 1.2-10.1 mg/dL [0.03-0.26 mmol/L]). CONCLUSIONS: Low-carbohydrate, non-energy-restricted diets appear to be at least as effective as low-fat, energy-restricted diets in inducing weight loss for up to 1 year. However, potential favorable changes in triglyceride and high-density lipoprotein cholesterol values should be weighed against potential unfavorable changes in low-density lipoprotein cholesterol values when low-carbohydrate diets to induce weight loss are considered.

Elevated levels of serum amyloid A (SAA) and C-reactive protein (CRP) have been associated with increased cardiovascular risk. Although levels of CRP decrease with weight loss, it is not known whether SAA decreases with weight loss or whether dietary macronutrient composition affects levels of either SAA or CRP. SAA and CRP levels were measured retrospectively on baseline and 3-month plasma samples from 41 obese (mean body mass index 33.63 +/- 1.86 kg/m2) women completing a randomized trial comparing a low-fat diet (n = 19) and a very low-carbohydrate diet (n = 22). For the 41 participants, there were significant decreases from baseline to 3 months in both LogSAA (P = 0.049) and LogCRP (P = 0.035). The very low-carbohydrate dieters had a significantly greater decrease in LogSAA (P = 0.04), but their weight loss also was significantly greater (-7.6 +/- 3.2 vs. -4.3 +/- 3.5 kg, P < 0.01). In this study, the decreases in inflammatory markers correlated significantly with weight loss (r = 0.44, P = 0.004 vs. LogSAA and r = 0.35, P = 0.03 vs. LogCRP). Also, change in LogSAA correlated with change in insulin resistance (r = 0.35, P = 0.03). Thus, in otherwise healthy, obese women, weight loss was associated with significant decreases in both SAA and CRP. These effects were proportional to the amount of weight lost but independent of dietary macronutrient composition.
