Relationship between alcohol intake and dietary pattern: Findings from NHANES III

AIM: To examine the association between macronutrient dietary patterns and alcohol consumption using the Third National Health and Nutritional Examination Survey III. METHODS: A total of 9877 subjects (5144 males) constituted the study cohort. Dietary interviews were conducted with all examinees by a trained dietary interviewer in a mobile examination center (MEC). Subjects reported all foods and beverages consumed except plain drinking water for the previous 24-h time period. Physical examination and history of alcohol consumption were obtained. Pearson correlation coefficients were used to evaluate the association of the levels of alcohol consumption and the percentage of energy derived from macronutrients. Univariate and multivariate regression analyses were performed accounting for the study sampling weight to further explore the relationships between alcohol consumption and calories derived from each macronutrient. RESULTS: Subjects who drank were younger than non-drinker controls in both genders (P < 0.01). Alcohol intake was inversely associated with body mass index and body weight in women. Of all macronutrients, carbohydrate intake was the first to decrease with increasing alcohol consumption. In the multivariate analyses, the level of alcohol consumption was found to be an independent predictor associated with lower intake of other macronutrients. CONCLUSION: Our results show that there is an alteration in the daily dietary pattern with increasing alcohol consumption and that energy derived from alcoholic beverages substitutes that from other macronutrients such as carbohydrate, protein, and fat

Dietary fat and total energy intake modifies the association of genetic profile risk score on obesity: evidence from 48 170 UK Biobank participants

Background: Obesity is a multifactorial condition influenced by both genetics and lifestyle. The aim of this study was to investigate whether the association between a validated genetic profile risk score for obesity (GPRS-obesity) and body mass index (BMI) or waist circumference (WC) was modified by macronutrient intake in a large general population study. Methods: This study included cross-sectional data from 48 170 white European adults, aged 37–73 years, participating on the UK Biobank. Interactions between GPRS-obesity, and macronutrient intake (including total energy, protein, fat, carbohydrate and dietary fibre intake) and its effects on BMI and WC were investigated. Results: The 93-SNPs genetic profile risk score was associated with a higher BMI (β:0.57 kg.m−2 per standard deviation (s.d.) increase in GPRS, [95%CI:0.53–0.60]; P=1.9 × 10−183) independent of major confounding factors. There was a significant interaction between GPRS and total fat intake (P[interaction]=0.007). Among high fat intake individuals, BMI was higher by 0.60 [0.52, 0.67] kg.m−2 per s.d. increase in GPRS-obesity; the change in BMI with GPRS was lower among low fat intake individuals (β:0.50 [0.44, 0.57] kg.m-2). Significant interactions with similar patterns were observed for saturated fat intake (High β:0.66 [0.59, 0.73] versus Low β:0.49 [0.42, 0.55] kg.m-2, P-interaction=2 × 10-4), and total energy intake (High β:0.58 [0.51, 0.64] versus Low β:0.49 [0.42, 0.56] kg.m−2, P-interaction=0.019), but not for protein intake, carbohydrate intake and fiber intake (P-interaction &gt;0.05). The findings were broadly similar using WC as the outcome. Conclusions: These data suggest that the benefits of reducing the intake of fats and total energy intake, may be more important in individuals with high genetic risk for obesity

Carbohydrate Intake in the Etiology of Crohn's Disease and Ulcerative Colitis

Background: Diet may have a role in the etiology of inflammatory bowel disease. In previous studies, the associations between increased intakes of carbohydrates, sugar, starch, and inflammatory bowel disease are inconsistent. However, few prospective studies have investigated the associations between these macronutrients and incident Crohn's disease (CD) or ulcerative colitis (UC). Methods: A total of 401,326 men and women were recruited between 1991 and 1998. At recruitment, dietary intakes of carbohydrate, sugar, and starch were measured using validated food frequency questionnaires. The cohort was monitored identifying participants who developed incident CD or UC. Cases were matched with 4 controls, and odds ratios were calculated for quintiles of total carbohydrate, sugar, and starch intakes adjusted for total energy intake, body mass index, and smoking. Results: One hundred ten participants developed CD, and 244 participants developed UC during follow-up. The adjusted odds ratio for the highest versus the lowest quintiles of total carbohydrate intake for CD was 0.87, 95% CI = 0.24 to 3.12 and for UC 1.46, 95% CI = 0.62 to 3.46, with no significant trends across quintiles for either (CD, Ptrend = 0.70; UC, Ptrend = 0.41). Similarly, no associations were observed with intakes of total sugar (CD, Ptrend = 0.50; UC, Ptrend = 0.71) or starch (CD, Ptrend = 0.69; UC, Ptrend = 0.17). Conclusions: The lack of associations with these nutrients is in agreement with many case–control studies that have not identified associations with CD or UC. As there is biological plausibility for how specific carbohydrates could have an etiological role in inflammatory bowel disease, future epidemiological work should assess individual carbohydrates, although there does not seem to be a macronutrient effect

An investigation of the breakfast habits and dietary intakes of year 8 Auckland children : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Nutritional Science at Massey University

Breakfast is often referred to as the most important meal of the day. Studies have consistently shown that regular breakfast consumption makes a significant contribution to nutrient intake. Additionally, individuals who have skipped breakfast often do not make up for the missed nutrients during the remainder of the day. Results from the National Children's Nutrition Survey show that breakfast consumption varies with ethnicity and age. In particular, Pacific Island children and older children were less likely than other ethnic and age groups to have breakfast. The overall aim of the current study was to collect detailed information on dietary intake, breakfast habits, choices, and preferences of intermediate school children. Two multi-cultural decile six intermediate schools in North Shore City, Auckland were selected to participate. A dietary assessment of over two hundred students (12-13 years of age) was completed using a dietary recall methodology. Data were also collected on breakfast habits and preferences, and anthropometric measurements made. A subset group of 52 students was randomly selected to provide detailed information on their nutrient intake. Each student within the subgroup completed two 24-hour recalls during the school week, and a food diary on a Saturday. Findings from this research showed that both male and female students had a high level of breakfast consumption, with over half of the students reporting that this represented their daily habit. Overall, only 4% reported that they rarely or never have breakfast. The most reported reason given for skipping breakfast was not being hungry in the morning, followed by preferring to sleep in, and then lack of time. There was some evidence from this study that the daily commitments of family members (e.g., working parents) may influence breakfast eating habits. Additionally, it is likely that the availability of preferred breakfast foods at home contributed to high breakfast consumption observed in this study population. Interestingly, breakfast consumption was not significantly associated with gender, but was however influenced by ethnicity, with Maori/Pacific Island children less likely to eat breakfast than children of other ethnic groups (P = 0.001). Breakfast skippers had a significantly higher body mass index (BMI) compared to breakfast eaters, although further research is required to assess the association between habitual breakfast consumption and BMI. The majority of breakfast consumers chose foods and beverages that contributed to a balanced breakfast. Of those subjects who had breakfast, over 60% consumed a cereal, with the most popular being Weet-Bix. Findings from the subgroup analysis showed that the consumpton of breakfast made a significant contribution to the daily intake of nutrients such as iron, calcium, folate, riboflavin, and thiamin, for both male and female breakfast eaters. The information gained from this study may facilitate the implementation of nutrition education and intervention programmes designed to improve eating patterns (in particular breakfast consumption) and the dietary intake of children and adolescents. Promoting and maintaining good breakfast habits in children of this age group may lead to improved breakfast consumption patterns and health as they progress through adolescence

The use of management accounting practices in Malaysian SMEs

There have been the recent calls for additional research in order to enhance the understanding of the adoption of management accounting practices (MAPs) in small and medium sized enterprises (SMEs). This, allied to an increasing importance of SMEs around the world especially in developing countries, is the motivation for this research. This research explores the uptake of a broad range of MAPs in Malaysian SMEs; identifies the roles of MAPs in the management of SMEs; determines factors that affect the extent of use of MAPs in SMEs and lastly examines the relationship between the use of MAPs and organizational performance of SMEs. A postal questionnaire was conducted to 1,000 Malaysian SMEs in manufacturing sector which elicited 160 useable responses. The results show that the majority of respondents have used the five management accounting areas identified. Use of the costing system, budgeting system and performance evaluation system are significantly higher than for the decision support system and strategic management accounting, which indicates that the uptake of traditional MAPs is greater than for sophisticated MAPs. The results indicate that medium sized firms make greater use of all MAPs as opposed to small sized enterprises. The most significant differences relate to the use of decision support system and strategic management accounting. The increased uptake of sophisticated MAPs by larger firms is in line with size being a contingent variable explaining the use of such practices. The results also suggest that MAPs were perceived as playing very important roles in the management of Malaysian SMEs. Performance evaluation and controlling activities were the major roles of MAPs in the management of SMEs. Overall the study suggests that MAPs are perceived by SMEs as relevant and useful in their management processes. Further, the study found that four out of five contingent factors; size of the firm, intensity of market competition; participation of the owner/manager in the development of MAPs in firm and advanced manufacturing technology have a positive and statistically significant relationship with the use of certain MAPs. The research however found weak support for the positive relationship between the use of MAPs and organizational performance of SMEs. This study enriches the existing body of knowledge of management accounting by providing information as to the use of MAPs in SMEs in Malaysia. The findings can be specifically informative for policy makers intent on developing management accounting skills among Malaysian SMEs. This research will provide valuable insights into the nature of MAPs in SMEs in a developing country and will promote interest among Malaysian researchers as well as researchers of other countries to make the SME sector a focus of interest in management accounting researc

Dairy foods and dairy protein consumption is inversely related to markers of adiposity in obese men and women

A number of intervention studies have reported that the prevalence of obesity may be in part inversely related to dairy food consumption while others report no association. We sought to examine relationships between energy, protein and calcium consumption from dairy foods (milk, yoghurt, cheese, dairy spreads, ice-cream) and adiposity including body mass index (BMI), waist (WC) and hip circumference (HC), and direct measures of body composition using dual energy X-ray absorptiometry (% body fat and abdominal fat) in an opportunistic sample of 720 overweight/obese Australian men and women. Mean (SD) age, weight and BMI of the population were 51 ± 10 year, 94 ± 18 kg and 32.4 ± 5.7 kg/m2, respectively. Reduced fat milk was the most commonly consumed dairy product (235 ± 200 g/day), followed by whole milk (63 ± 128 g/day) and yoghurt (53 ± 66 g/day). Overall dairy food consumption (g/day) was inversely associated with BMI, % body fat and WC (all p < 0.05). Dairy protein and dairy calcium (g/day) were both inversely associated with all adiposity measures (all p < 0.05). Yoghurt consumption (g/day) was inversely associated with % body fat, abdominal fat, WC and HC (all p < 0.05), while reduced fat milk consumption was inversely associated with BMI, WC, HC and % body fat (all p < 0.05). Within a sample of obese adults, consumption of dairy products, dairy protein, and calcium was associated with more favourable body composition

The influence of macronutrients on cognitive performance : effects across age and task difficulty : thesis presented in partial fulfillment of the requirements for the degree of Master of Arts in Psychology at Massey University

The effects of pure glucose, protein, and fat ingestion on tasks of paragraph recall, word recall, and mental arithmetic were examined. These effects were also investigated with regard to the age of the participant and the task difficulty level. Twelve young and twelve older adults participated in the study. Over four separate morning sessions, participants ingested one of the four drinks (glucose, protein, fat, or placebo), and completed easy and hard versions of the paragraph recall word recall, and mental arithmetic tasks. The between-group factor was Age of the participant (young or older adult). The within-group factors were type of Nutrient ingested (glucose, protein, fat, or placebo), and Difficulty Level (easy or hard). No effects of Nutrient were found in regard to overall task performance, collapsing across Age and Difficulty Level. There was no effect of Nutrient on the different performance levels of both age groups, or for the two task difficulty levels. However, post-hoc analyses did reveal a significant Nutrient x Age interaction for the elderly after ingestion of the protein drink. Trends in the data also pointed towards an enhancement effect of glucose for the paragraph recall and mental arithmetic tasks. Trends associated with performance levels after fat ingestion showed that fat tended to enhance mental arithmetic accuracy performance for the older adult age group. Protein did not appear to differ from placebo on any of the tasks, with the exception of the deficit in performance seen with the elderly on the mental arithmetic accuracy task. In addition, a post-hoc analysis of the effects of Nutrient on mood-state showed a significant Nutrient x Mood x Time interaction. These results were discussed in light of task-specific effects of nutrients and nutrient metabolism

Beyond Scope of Practice: Inferring High School Tennis Coaches' Behavior from their Nutrition and Eating Disorder Knowledge

The primary purpose of this study was to assess high school tennis coaches’ knowledge of macronutrients and disordered eating (e.g., etiology). Other purposes included identifying confidence in knowledge and any differences between the participating coaches’ knowledge and demographic variables. To address these purposes, the 27-question Nutrition and Eating Disorders in Tennis (“NET”) Survey was created. The study design involved a one-time voluntary assessment of the Indiana coaches’ demographic variables, knowledge, sources of knowledge, and level of confidence (e.g., Not At All or Very Confident). Overall, the results revealed that the coaches lacked knowledge. The average score was 70.6%, which was below the criterion for adequate knowledge. Furthermore, the coaches lacked adequate knowledge in three of the five knowledge domains: Treatment and Prevention of Disordered Eating (63.6% ± 22.9%), Disordered Eating Signs and Symptoms (60.0% ± 21.7%), and Macronutrients (57.0% ± 22.4%). There were no significant differences between coaches’ education level, gender, or type and knowledge. However, there was in experience; the more years coached, the lower the scores. Finally, there was a trend of overconfidence in answers
