Evaluation of nutritional status and adherence to dietary monitoring among patients with human T-cell leukemia virus type 1 infection

BACKGROUND & AIMS

The nutritional status of people infected with Human T-Cell Leukemia Virus type 1 (HTLV-1) is rarely studied. Malnutrition affects the immune system, but the consequences of this remain unknown in HTLV-1 infection. This study aimed to analyze the nutritional status, food intake, and ability to adhere to dietary counseling in people with symptomatic HTLV-1 infection.

METHODS

This was a longitudinal, prospective, observational study in which the nutritional status of people with symptomatic HTLV-1 was monitored between June 2016 and August 2019 at a referral center. At the baseline (day 0) and last stage (day 90) anthropometric, bioimpedance, and dietary assessments were performed.

RESULTS

In total, 71 participants with symptomatic HTLV-1 infection were enrolled, the majority (43, 60.6%) of whom were female. The mean age was 59.2 (±11.1) years. Participants were often overweight or obese (40, 56.3%) had a BMI above 25 kg/m². The average consumption of recommended fibers and liquids was positively associated with percent lean body mass (%LM). Most participants who were overweight (36.6%) or obese (19.70%) and their nutritional status and eating behavior did not change during the follow-up period. Dietary counseling was unable to promote a change in the monotony of the existing eating habits. Participants with good adherence to nutritional guidelines had higher dietary diversity scores.

CONCLUSION

A high proportion of participants were overweight or obese. Adherence to dietary counseling was low, and its success was limited in improving dietary diversity/nutritional status. Loss to follow-up was a limitation of this study.

The prevalence of and factors associated with constipation in elderly residents of long stay institutions

Objective : Constipation is a frequent motility disorder and while a common complaint among the overall population, is particularly prevalent among the elderly. The increase of this population group is creating a growing demand for long term care institutions. The present study aims to investigate the prevalence of and factors associated with constipation in elderly residents of long stay care institutions. Method : The study involved 87 individuals. The data collected from each participant included gender, daily intake of water and fiber, physical activity, family history of constipation and nutritional status. The diagnosis of constipation was based on Roma III criteria. Statistical analysis was performed with the SPSS software program (version 18.0) with a level of significance of 5% (p≤0.05). The Student t, Mann-Whitney, Pearson's chi-square or Fischer's exact tests were employed. Results : The sample was predominantly female (80.5%), with a mean age of 79.4(±9.6) years. A 42.52% prevalence of constipation was observed. Among affected individuals, the condition was more frequent among women (89.2%), those aged over 80 years (67.6%), those who did not engage in physical activity (56.8%), those with below the recommended intake of water and fiber, those who had a family history of constipation, and those who were diagnosed with eutrophia (56.3%). Among the factors analyzed, only age (p=0.049) and low fiber intake (p=0.019) were significantly linked to constipation. Conclusion : The results show that constipation is a multifactorial disease that is significantly related to age and low fiber intake.
