RESUMEN
Proteins are needed for providing essential amino acids, nitrogen, and fuel for the body's needs in all age groups. Proteins are especially required during active growth in pregnancy, lactation, childhood, and tissue growth in general. An adequate protein intake is needed in old adults to avoid premature muscle loss. According to the current dietary surveys, protein intake in the Nordic and Baltic countries varies from 15 to 19% of the total energy intake in adults. Comprehensive data regarding children and older adults are lacking. No good measure for protein status exists, and the estimation of physiological requirements is based on N-balance studies having some weaknesses. Protein quality is assessed by considering the protein digestibility of individual indispensable amino acids and their utilization (bioavailability), which is affected by food antinutrients and processing. The evidence regarding the association of protein intake per se with health outcomes is limited or suggestive. It is difficult to separate from the effect of other nutrients or ingredients in protein-rich foods. Proteins are widespread in foods, deriving from both animal and plant sources. Animal-sourced protein production puts more strain on the environment than plant-sourced proteins and contributes significantly to greenhouse gas emissions, thereby enhancing climate change. In Nordic and Baltic countries, consumption of animal-sourced proteins is relatively high. A shift toward more plant-based protein diets would be advisable for promoting a healthy and sustainable diet.
RESUMEN
INTRODUCTION: Prevalence of oral health problems among nursing home residents is common, they suffer from oral diseases and need dental service. The aim of this study was to examine clinical oral health of Icelandic nursing home residents and their oral health quality of life. MATERIAL AND METHODS: Total (N=82) residents in two nursing homes in Reykjavik gave their consent to be involved in this descriptive cross-sectional study. Residents participated in a clinical oral health examination at site and answered oral health quality of life questionnaire. RESULTS: Total 89% (N=73) residents completed the study, mean age 86.8 years (SD=5.7, range 73-100 years), of whom third had their own teeth and like had teeth, and partial dentures, while 41.1% were completely edentulous. The clinical oral health examination showed high prevalence of untreated oral health problems (67%). Residents with the worst oral health scored significantly higher than those who were better dentate, affecting their oral health quality of life (p=0.014), functional limitation (p=0.002) and physical disability (p=0.000). Most oral health problems interrelated to chewing, eating and limited ability to eat certain foods affecting their capability of food intake. CONCLUSION: Current administration of oral health care in nursing home needs alteration and the qualification in geriatric oral health and oral health care must be guaranteed among nursing staff in these settings. The public and health professions should work together in oral care matters in nursing homes to maintain oral health and lifelong oral health quality of life among residents.

OBJECTIVES: To assess oral care beliefs and oral hygiene procedures among nursing home personnel to identify strengths and weaknesses in managing oral care. METHODS: A cross-sectional study in two nursing homes using an oral health care questionnaire including the Nursing Dental Coping Belief Scale. RESULTS: A total of 109 health personnel participated. Oral care was seldomly achieved twice a day and dental supplies were not guaranteed. Registered nurses found the oral health of residents more acceptable than did allied health personnel with less oral care education, who mostly delivered daily care. Conversely, nursing staff with oral care education had lower dental coping beliefs, suggesting a lack of self-reliance in controlling oral health outcomes. CONCLUSION: Dental supplies should be part of nursing care equipment. Educational programs could increase positive oral health beliefs and enhance the quality of care in these settings, particularly among those who are accountable for oral care.

INTRODUCTION: Oral nutrition support is frequently used in treatment of malnutrition in patients with chronic obstructive pulmonary disease (COPD). Considering the use of corticoidsteroids in patients with COPD, little is known about the effect on postprandial glucose response and if they might interfere with glucose control. Our aims were to compare the effect of a liquid oral nutritional supplement (ONS) and semi solid inbetween meal snack (snack) on postprandial glucose and energy- and protein intake, and to compare the effect of timing of each intervention on postprandial glucose and energy- and protein intake. METHODS: Patients with COPD (n = 17) admitted to the Department of Pulmonary Medicine, Iceland and defined as at low or medium nutritional risk (score 0-3) were recruited. In a randomised cross-over design, subjects consumed ONS or snack either in a fasting state (study 1) or following breakfast (study 2) and postprandial glucose responses were assessed at regular intervals for two hours (t = 15, t = 30, t = 45, t = 60, t = 90, t = 120 min). Energy- and protein intake was estimated using a validated plate diagram sheet. Wilcoxon Signed-Rank test was used to compare the two interventions. RESULTS: In study 2, following breakfast, postprandial glucose was significantly higher after consuming ONS than the snack after 60 min (9.7 ± 2.4 mmol/L vs. 8.2 ± 3.2 mmol/L, p = 0.013 and 120 min 9.2 ± 3.2 mmol/L vs. 7.9 ± 2.4 mmol/L, p = 0.021, respectively). No difference was found in postprandial glucose concentrations between ONS and the snack when consumed after overnight fasting (study 1). No difference in energy or protein intake from hospital food was seen between supplement types neither in study 1 or 2. CONCLUSION: Lower postprandial glucose concentrations were associated with the snack compared to ONS when taken after a meal compared to either type directly after overnight fasting. The clinical relevance of higher postprandial blood glucose after consuming a liquid ONS after breakfast compared with a semi solid snack needs to be studied further.

The purpose of the study was to investigate the association between baseline cognitive function and improvement in mobility after 12 weeks of resistance training (3 times/week; 3 sets, 6-8 repetitions at 75-80% of the 1-repetition maximum) among community-dwelling older adults in Iceland (N=205, 73.5±5.7 years, 57.0% female). Body composition, physical activity status, cardiovascular risk factors, 6-minute walk test (6MWT), and Mini-Mental State Examination (MMSE) were measured. The linear regression model was used to examine the association between baseline MMSE and mobility improvement. Mean distance of 6MWT was 462.8±71.6 meter at baseline and mean change after the exercise intervention was 33.7±34.9 meter. The mean MMSE score at baseline was 27.6±1.9. After adjusting for baseline covariates, we found that baseline MMSE score was significantly associated with improvement in mobility among older adults after the exercise intervention. Cognitive function strongly influences the effect of exercise intervention on mobility among older adults.

Introduction: Intervention studies have mainly used oral nutritional supplements (ONS) for the management of patients with chronic obstructive pulmonary disease (COPD) identified as at nutritional risk. In this 12-month randomised feasibility trial, we assessed the (1) feasibility of the recruitment, retention and provision of two interventions: ONS and between-meal snacks (snacks) and (2) the potential impact of the provision of snacks and ONS on body weight and quality of life in patients with COPD. Methods: Hospitalised patients with COPD, at nutritional risk, were randomised to ONS (n=19) or snacks (n=15) providing 600 kcal and 22 g protein a day in addition to regular daily diet. The intervention started in hospital and was continued for 12 months after discharge from the hospital. Results: Study recruitment rate was n=34 (45%) and retention rate at 12 months was similar for both groups: n=13 (68%) in the ONS group and n=10 (67%) in the Snacks group. Both groups gained weight from baseline to 12 months (2.3±4.6 kg (p=0.060) in the ONS group and 4.4±6.4 kg (p=0.030) in the Snacks group). The St George's Respiratory Questionnaire total score improved from baseline to 12 months in both groups (score 3.9±11.0 (p=0.176) in the ONS group and score 8.9±14.1 (p=0.041) in the Snacks group). Discussion: In patients with COPD who are at nutritional risk snacks are at least as feasible and effective as ONS, however, adequately powered trials that take account of the difficulties in recruiting this patient group are required to confirm this effect.

INTRODUCTION: Low fat free mass index (FFMI) is a component of the ESPEN diagnosis criteria of malnutrition, that only when accompanied with weight loss is considered to be a determinant of malnutrition. Our aims were to assess the prevalence of malnutrition in patients with chronic obstructive pulmonary disease (COPD) applying the ESPEN criteria, and to examine the ability of different components of the criteria to predict COPD severity, length of stay (LOS), hospital readmissions within 30 days and mortality. METHODS: Subjects were COPD patients (n = 121) admitted to Landspitali University Hospital from March 2015 to March 2016. Patients were screened for nutritional risk using Icelandic screening tool (ISS) and NRS-2002. Body composition was measured by bioelectrical impedance analysis (BIA). Lung function was measured by spirometry. RESULTS: The prevalence of malnutrition according to the ESPEN criteria was 21%. The association between nutritional assessment, applying different components of the ESPEN criteria, and COPD severity was highly significant, with the highest risk being associated with low FFMI OR (95% CI) 4.77 (2.03, 11.20; p < 0.001). There was a trend towards higher risk of hospitalization for >7 days in subjects with low FFMI (OR 2.46 95% CI 0.92, 6.59; p = 0.074) and increased risk of 6 and 9 months' mortality (OR 2.72 95% CI 0.88, 8.39, P = 0.082 and OR 2.72 95% CI 0.94, 7.87, P = 0.065, respectively) in subjects diagnosed as malnourished by the ESPEN criteria. CONCLUSION: This study describes the prevalence of malnutrition in hospitalized COPD patients using the ESPEN criteria from 2015. Our findings suggest that FFMI could be used independently of weight loss for the diagnosis of malnutrition in COPD patients, although there remain some problems associated with its measurement in the clinical setting.

INTRODUCTION: The prevalence of lifestyle related diseases is higher among people with psychotic disorders than the general population. The aim was to assess dietary intake of young people with psychotic disorders for the first time in Iceland. MATERIAL AND METHODS: Subjects were young people (n=48, age 18-30y) with psychotic disorders. Dietary intake was assessed by a 24-hour recall in July-August 2016, and compared with official recommendations and intake of the general public (n=250, age 18-30y). Body weight in the past eight to 12 months, was retrieved from medical records. RESULTS: Consumption of fruits, fish, dairy products, vegetable and fish oil was significantly lower among subjects when compared with the general public, while their soft drink and sweets consumption was higher (p<0.001). Furthermore, the contribution of added sugar was higher (15E% vs. 12E%) and protein intake lower (16E% vs. 18E%). Consumption of omega-3 fatty acids and vitamin D was lower among subjects than the general public and lower than recommended (0.04±0.3% omega-3 of total energy vs. 1.2±0.6%, p<0.001 and 3.1±4.2 µg vitamin D/day vs. 5.6±6.5 µg/day, p<0.001). Almost 40% of the subjects had gained >5% of their initial body weight in the past 8-2 months. CONCLUSION: Diet of young people with psychotic disorders is not consistent with recommendations and is worse than the diet of their peers in the general population. It is important to find ways to improve the diet and thereby nutrient intake of the group. Key words: psychotic disorders, schizophrenia, recommended dietary allowances, fatty acids, omega-3, vitamin D. Correspondence: Ingibjorg Gunnarsdottir, ingigun@landspitali.is.

AIMS: Benefits of resistance exercise in elderly people are well documented; however, sustaining these benefits can be difficult and adherence is often poor. Muscular strength and physical function usually decline after a supervised resistance exercise program (REP). We investigated these changes in older adults during an observational follow-up and whether leisure time physical activity (LTPA) or unsupervised resistance exercise (RE) limit these changes. METHODS: Subjects (N = 236, 73.7 ± 5.7 years, 58.2% female) had participated in a supervised 12-week REP. Quadriceps strength and timed-up-and-go performance (TUG) at follow-up were compared to values before and after REP. Multivariate statistics were used to predict changes in strength or function. RESULTS: Two hundred and eleven (90.3%) participants completed REP and 149 (63.1%) completed follow-up (11.4 ± 2.9 months). Quadriceps strength at follow-up decreased significantly compared to after REP (-27N), but was higher than before REP (+ 30N). TUG did not decrease during follow-up and was better than before REP (-0.9 seconds). LTPA (+ 38.0N, p < 0.001) and RE (+31.6N, p = 0.006) predicted strength at follow-up, although they did not completely prevent loss of strength during follow-up. CONCLUSIONS: quadriceps strength declines after a 12-week resistance exercise program in older adults. Neither LTPA nor RE completely prevents loss of quadriceps strength during follow-up, although they limited the loss. TUG did not change during follow-up and was better at follow-up than before the start of the resistance exercise program.

INTRODUCTION: Old people attend emergency departments (ED´s) in increasing numbers. Old people have age related changes in all organ systems and tend to have multiple chronic diseases, be on multiple medications and often have physical and cognitive functional impairments. Hence, they have complex health and social service needs. The purpose of this study was to describe function and geriatric syndromes of old people who present at Landspitali Emergency Department, Iceland, with comparison to ED´s in six other countries. MATERIAL AND METHODS: A prospective descriptive study of people (>75 year´s) attending ED´s in seven countries, including Iceland. The InterRAI assessment tool for ED´s was used by nurses to assess participants. RESULTS: At Landspitali ED, 202 individuals were assessed, of whom 55% were women. Of the 202 individuals, 34% attended the ED within 90 days and of those 48% lived alone. On admission to the ED, 59% had physical or cognitive functional impairment; 13% had only cognitive impairment and 36% were unable to walk without assistance. Caregiver distress was identified in 28% and 11% felt overwhelming burden. From the ED, 46% were admitted to the hospital. Compared with foreign results greater number of Icelandic participants lived alone and caregiver's distress was slightly higher (28% vs. 18%). Fewer individuals in Iceland were admitted to a hospital and Iceland had higher admission rate to rehabilitation compared with the overall group. CONCLUSION: Geriatric syndromes and functional impairment afflicted majority of old people who attended the Landspitali ED. These observations should be taken into account in ED design and care planning for old people to maximize efficiency, safety and quality.

OBJECTIVE: Prevalence of hypertension, which is the most common risk factor for cardiovascular disease in elderly people, increases with age. The aim of the study was to investigate the association between diet and blood pressure in elderly Icelanders, with focus on cod liver oil, and to compare their diet to dietary guidelines. MATERIAL AND METHODS: Diet was assessed using three-day weighed food records and blood pressure was measured after a 12-hour-fast in 236, 65-91 years old, Icelanders living in the capital area of Iceland. 99 men (42%) and 137 women (58%) participated in the study. RESULTS: According to Nordic nutrition recommendations, intake of nutrients was above lower intake levels among the majority of participants. However, 19% were under this level for vitamin-D, 13% for iodine, 17% of men for vitamin-B6, and 26% and 12% of men and women, respectively, for iron. Systolic blood pressure was inversely associated with cod liver oil intake, even when adjusted for age, body mass index, gender, and antihypertensive medications (P=0.01). Intake of long-chain omega-3 fatty acids correlated with blood pressure in a similar way. Other dietary factors were not associated with blood pressure. CONCLUSION: The results indicate that intake of cod liver oil is associated with lower blood pressure among elderly people and may therefore have beneficial effects on health. A notable proportion of participants was at risk of vitamin D, vitamin B6, iodine, and iron deficiency.
