Coeliac disease: the association between quality of life and social support network participation

BACKGROUND

There is little information available on the use of social support systems for patients with coeliac disease (CD). We performed a cross-sectional study aiming to examine the association between participation in different types of social support networks and quality of life (QOL) in adults with CD.

METHODS

A survey including a validated CD specific QOL instrument was administered online and in-person to adults with CD who were following a gluten-free diet. Participation in social support networks (type, frequency and duration) were assessed.

RESULTS

Among the 2138 participants, overall QOL scores were high, averaging 68.9 out of 100. Significant differences in QOL scores were found for age, length of time since diagnosis and level of education. Most (58%) reported using no social support networks. Of the 42% reporting use of social support networks (online 17.9%, face-to-face 10.8% or both 12.8%), QOL scores were higher for those individuals who used only face-to-face social support compared to only online support (72.6 versus 66.7; P < 0.0001). A longer duration of face-to-face social support use was associated with higher QOL scores (P < 0.0005). By contrast, a longer duration and increased frequency of online social support use was associated with lower QOL scores (P < 0.03).

CONCLUSIONS

Participation in face-to-face social support networks is associated with greater QOL scores compared to online social support networks. These findings have potential implications for the management of individuals with CD. Emphasis on face-to-face support may improve long-term QOL and patient outcomes.

Short-term patient-centered nutrition counseling impacts weight and nutrient intake in patients with systemic lupus erythematosus

BACKGROUND

Patients with systemic lupus erythematosus (SLE) are at a high risk for cardiovascular disease (CVD) due to increased prevalence of traditional and nontraditional CVD risks factors.

OBJECTIVE

To evaluate the effect of patient-centered nutrition counseling methods on changes in select nutrient, anthropometric, and clinical outcomes in SLE patients enrolled in a CVD prevention counseling program (CVD PCP).

METHODS

From March 2009 to June 2011 a subgroup of SLE patients enrolled in our CVD PCP were referred to a registered dietitian for individualized nutrition counseling. Outcomes of interest were assessed at baseline and six months. A primary analysis evaluated the six-month changes in nutrient intake, weight, body mass index (BMI), waist circumference, and lipid levels. A secondary analysis compared the same measurements between the nutrition counseling patients and the group that was referred but did not attend.

RESULTS

Of 71 referrals, 41 (58%) attended nutrition counseling (female: 89%, African American/Hispanic: 72%, mean age of 39.7 ± 12.82 years, and a mean disease duration of 11.49 ± 8.02 years). Over a six-month period, patients attending nutritional counseling: (a) reduced their intake of sodium (p = 0.006), total calories (p = 0.07), and percent calories from fat (p = 0.011) and saturated fat (p = 0.068); (b) had decreased weight (-1.64 kg, p = 0.025); and (c) were more likely to report increases in eating a diet rich in fruits and vegetables (p < 0.001), a high fiber diet (p = 0.011), ≥two servings of fish/week (p = 0.002), and a low cholesterol diet (p = 0.034). There were no significant changes observed over the six months in BMI and clinical outcomes among nutrition counseling patients. When comparing nutrition counseling patients to those who were referred but did not attend, we found at six months a higher percentage of nutrition counseling patients reportedly followed a high-fiber diet (p = 0.03), consumed two or more servings of fish per week (p = 0.01), followed a low-cholesterol diet (p = 0.03), and achieved a greater weight loss (p = 0.04) compared to the group that did not attend.

CONCLUSION

At six months we found that nutrition counseling using patient-centered methods appears to be an effective method for promoting changes in nutrient intake, diet habits, and, possibly, anthropometric measures in SLE patients. However, the counseling did not show a significant improvement in lipid levels, possibly due to short follow-up and/or SLE related factors.

Post-diagnosis family adaptation influences glycemic control in women with type 2 diabetes mellitus

Family adaptation to type 2 diabetes management after nutrition education was studied as part of a 2.5-year ethnography. Data analysis included descriptive data (observations, transcribed audio recordings, written field notes) and quantitative data (self-monitored morning fasting blood glucose, food records) from the families of 5 New York suburban women. The following inferences emerged from data analysis. Among the women with improved glycemic control, the home and family routines had changed. Diabetes management was observed as certain tasks: food tasks, patient care tasks, management tasks, and medical advice tasks. The social context of the women's daily lives influenced their glycemic control; specifically, family members other than the women with diabetes took on new "hospital roles and routines." Nutrition education should be directed toward assessing existing family social support and helping women organize and supplement this support to ensure the successful completion of the tasks of diabetes self-management.

Relationships of dietary fat consumption to serum total and low-density lipoprotein cholesterol in hispanic preschool children

BACKGROUND

Studies of the relationship between dietary fat intake and serum lipids in young children have yielded inconclusive results. We studied this relationship in 108 Hispanic children ages 4-5 years.

METHODS

Four 24-hr recalls approximately 3 months apart and two Willett semiquantitative food frequency questionnaires approximately 6 months apart were obtained by interviewing the children's mothers. Diet measures were averaged for the multiple administrations of each of these instruments.

RESULTS

Based on the 24-hr recalls, children in the highest tertile of total fat consumption (36.2% of total calories) compared with the lowest tertile (30.2% of total calories) had mean total serum cholesterol of 4.32 mmol/liter (167 mg/dl) vs 3.91 mmol/liter (151 mg/d) (test for linear trend across tertiles, P less than 0.05) and mean low-density lipoprotein cholesterol of 2.74 mmol/liter (106 mg/dl) vs 2.29 mmol/liter (89 mg/dl) (test for linear trend, P less than 0.01). Children in the highest tertile of saturated fat consumption (14.6% of total calories) compared with the lowest tertile (11.2% of total calories) had mean total serum cholesterol of 4.39 mmol/liter (170 mg/dl) vs 3.97 mmol/liter (154 mg/dl) (test for linear trend, P less than 0.05) and mean low-density lipoprotein cholesterol of 2.80 mmol/liter (108 mg/dl) vs 2.35 mmol/liter (91 mg/dl) (test for linear trend, P less than 0.01). These relationships remained significant when calorie-adjusted nutrient intakes were examined and after adjustment in multiple linear regression models for age, sex, and body mass index, with the exception of the association of calorie-adjusted total fat with total serum cholesterol level (P = 0.07). Similar results were obtained using the Willett questionnaires.

CONCLUSIONS

These findings indicate that dietary fat, particularly saturated fat consumption, is an important correlate of blood lipid levels in preschool children. These are also the first reported data indicating that the Willett questionnaire, as a method for measuring the atherogenic components of diet, has criterion-related validity in young children.

Resting metabolic rate and energy balance in amenorrheic and eumenorrheic runners

This study investigated metabolic and nutritional factors in association with athletic menstrual dysfunction (AMD). Three groups of women were studied: amenorrheic runners (amenorrheic), eumenorrheic runners (eumenorrheic), and eumenorrheic sedentary controls (sedentary). Amenorrheic and eumenorrheic were similar in age, weight, percent body fat by hydrodensitometry, training pace and mileage, best 10 km race time, years running, and maximal oxygen consumption. When adjusted for body weight or for fat-free mass by analysis of covariance, RMR was significantly lower in amenorrheic than in eumenorrheic and sedentary. The daily caloric intakes of the groups did not differ significantly, but the amenorrheic scored significantly higher than the eumenorrheic and sedentary on a scale of aberrant eating patterns. Amenorrheic high mileage runners seem to have a less adequate diet than eumenorrheic runners but appear to maintain energy balance and stable weight through a reduction in RMR.

Blood pressure, fitness, and fatness in 5- and 6-year-old children

Cross-sectional relations among blood pressure (BP), aerobic fitness, body fatness, and fat patterning were studied in 216 primarily Hispanic inner-city 5- and 6-year-olds. Fitness was measured with a submaximal treadmill test, and fatness was measured with five skin folds. Diastolic BP was inversely related to fitness in the boys and girls, and positively related to fatness for the boys. Systolic BP was positively related to fatness for the boys and girls. Using multiple regression and including parental BPs, fatness explained significant proportions of the variance in systolic BP for both the boys and girls and in diastolic BP for the boys. There were tendencies for central skin folds to explain more of the variation in BP than peripheral skin folds only for the boys. Fitness and fatness were inversely related for the boys and girls. Thus, at 5 and 6 years of age children exhibit some of the same risk factors for cardiovascular disease seen in adults.

Failure of family history to predict high blood cholesterol among hispanic preschool children

Recommendations for screening children for high blood cholesterol remain controversial. The American Academy of Pediatrics, the American Heart Association, and the National Institutes of Health (NIH) Consensus Conference have recommended targeted screening of children with positive family history. We examined data from a sample of 108 Hispanic preschool children and their families to test targeted screening strategies. Thirty-seven children (34.3%) had total cholesterol levels of greater than or equal to 4.40 mmole/liter (170 mg/dl). Using the American Academy of Pediatrics definition of family history, sensitivity (proportion of those with high blood cholesterol with positive family history) was 0.57 (95% confidence interval, 0.40 to 0.73) and accuracy (overall proportion correctly classified) was 0.58 (0.48 to 0.68). Using the American Heart Association and NIH Consensus Conference definition of family history, sensitivity was 0.46 (0.30 to 0.63) and accuracy was 0.62 (0.52 to 0.71). Classification of children based on the mother's total cholesterol level of greater than or equal to 5.17 mmole/liter (200 mg/dl), the mother's low-density lipoprotein cholesterol level of greater than or equal to 4.14 mmole/liter (160 mg/dl), the mother's low-density lipoprotein cholesterol level of greater than or equal to 3.36 mmole/liter (130 mg/dl), or the child's own body mass index greater than or equal to 75th percentile was less sensitive and no more accurate. These findings indicate that current recommendations as well as other potential strategies for targeted cholesterol screening in young children have serious shortcomings and lend support to universal cholesterol screening in childhood.

Screening using National Cholesterol Education Program guidelines in a population of urban Hispanic mothers

We measured serum total cholesterol, high-density lipoprotein cholesterol, and triglycerides and calculated low-density lipoprotein cholesterol in 217 urban Hispanic mothers. On the basis of total cholesterol values, as recommended by the Expert Panel of the National Cholesterol Education Program, 6 subjects (2.8%) had high blood cholesterol (greater than or equal to 240 mg/dl), 27 (12.4%) had borderline-high blood cholesterol (200-239 mg/dl), and 184 (84.8%) had desirable blood cholesterol (less than 200 mg/dl). One of the 27 with borderline-high total cholesterol had two other coronary risk factors. Thus 7 of the 217 (3.2%, 95% confidence interval 1.4 to 6.8%) met Expert Panel criteria for lipoprotein measurement. Six of the seven had high-risk low-density lipoprotein cholesterol (greater than or equal to 160 mg/dl). Four additional subjects with borderline-high total cholesterol, not identified by this sequential screening strategy, also had high-risk low-density lipoprotein cholesterol. Thus a total of 10 of 217 (4.6%, 95% confidence interval 2.4 to 8.6%) met Expert Panel criteria for high-risk low-density lipoprotein cholesterol and initiation of cholesterol-lowering treatment. None of these 10 had been previously identified as having high-risk low-density lipoprotein cholesterol. Two years later subjects with high or borderline-high total cholesterol were rescreened. Seven of 22 subjects completing the second screening were classified differently with regard to having high-risk low-density lipoprotein cholesterol, illustrating the potential for misclassification of individuals on the basis of a single measurement. The prevalence of women with high-risk low-density lipoprotein cholesterol was not significantly different at the two screenings.(ABSTRACT TRUNCATED AT 250 WORDS)
