Abstract

Purpose

This study aims to evaluate the caffeinated drinks, levels of vitamin D and calcium in the blood, and their relationship to bone mineral density (BMD) in osteoporotic women in Al-Ahsa Saudi Arabia.

Design/methodology/approach

This study included 85 women over approximately 18 months with ages ranging from 40 to 70 years who were evaluated in the laboratory via blood analysis. Moreover, sociodemographic data and information on health and nutritional awareness were collected via a questionnaire. The BMD was measured by dual-energy X-ray absorptiometry (DXA) and considered osteopenia when the T value total of the lumbar spine or hip was between −1 and −2.5 and osteoporosis < −2.5. Blood levels of vitamin D and calcium were measured via blood analysis.

Findings

There were 54.1% and 45.9% of women who suffered from osteoporosis and low BMD, respectively. There was a significant difference in the number of osteoporotic, and low bone mineral mass groups in marital status (p = 0.04), but no difference was found in age and educational level. A significant difference (p = 0.01) between low bone mass and osteoporosis groups in heights. BMD was significantly and negatively correlated with vitamin D in the blood in individuals with osteoporosis (r = −0.358, P = 0.014). In addition, there was a significant negative correlation between calcium in the blood and total samples (r = −0.355, P = 0.0578). There was a negative significant relationship between calcium supplements and BMD in individuals with low BMD (rt = −0.279, P = 0.041). There was a significant association between cola intake with the occurrence of low BMD (p = 0.027), whereas tea drinking was not associated with risk in both groups.

Originality/value

The study indicated that there is a direct relationship between osteoporosis and low bone mass with different variables. This study was conducted to address the lack of research related to the levels of vitamin D and calcium in the blood and their relationship with BMD in women with low BMD and osteoporosis in Al-Ahsa province-KSA.

Abstract

Purpose

The intent of this review is to provide a nutritional background for the hypothesis that excessive intakes of calcium and, possibly, vitamin D in adults and the elderly may contribute to an increased risk of cardiovascular diseases.

Design/methodology/approach

Recent scientific reports and literature reviews on the linkage between excessive dietary calcium consumption and cardiovascular calcification have been assessed. Prospective human data on this health concern is limited to one recent report from New Zealand of elderly women on calcium supplements for five years. Other supporting evidence is derived from experimental studies over the years and from observations of subjects with gastric ulcers who consumed excessive amounts of milk along with antacids and of “worried well” subjects who took excessive calcium supplements or yogurt.

Findings

Calcium loading in arterial walls occurs under these conditions, even among those with healthy renal function, because atherosclerotic plaques in arterial intimal layers readily permit calcium uptake from blood and the formation of bone in inappropriate locations throughout the body, especially in coronary arteries, heart valves, and arteries of other major organs. Arteriosclerotic damage in affluent populations, such as the USA, is common. Bone health seems to benefit little from excessive calcium in late life compared to the damage to arterial function.

Research limitations/implications

Future studies are needed to advance understanding of this diet‐disease linkage.

Originality/value

This review supports recent data that indicates an important relationship between excessive calcium intakes and arterial calcification in adults and the elderly.

Abstract

This case looks at an important business task: forecasting a new product. The case can be used to teach finance, marketing (new product introduction), and healthcare strategy. The product is one of Amgen's most important new products: denosumab. On the surface, the case is fairly easy; students simply have to do some simple mathematical calculations. However, the challenges of forecasting quickly become apparent; every forecast depends on some critical assumptions, and the answer can vary dramatically.

Highlight the importance of forecasting as a business task. Give students the opportunity to create a forecast, using logical assumptions to generate an answer. Illustrate how dramatically forecasts can vary. Demonstrate why sensitivity analysis and customer understanding are both critical when trying to forecast a new product launch.

Abstract

A recent national survey raised concern about the diets and lifestyle habits of young women. Whilst nutrient intakes among the younger groups were generally adequate, some girls aged 15‐18 years had low intakes of many nutrients including vitamin A, folate, zinc, iron and calcium and low vitamin D status and ferritin levels. Of girls of this age, 16 per cent were dieting to lose weight and energy intake was low in relation to the estimated average requirement. Moreover, 69 per cent were not meeting the Health Education Authority recommendation for moderate activity levels. In response to these findings the British Nutrition Foundation held a one‐day conference to discuss current nutrition and lifestyle issues for younger women.

Abstract

This study was designed to assess the physical fitness and health status in 36 life‐long vegetarians. Besides a general questionnaire a dietary diary was completed and several blood parameters were determined. Physical fitness profile was estimated by testing handgrip strength, leg explosive strength, dynamic abdominal muscle endurance and cardiorespiratory endurance capacity. Body mass and length were measured for the determination of the BMI. The general questionnaire revealed that most of the subjects had healthy lifestyles. Nutritional intakes were not optimal with excess of some nutrients, but equally with some intakes not reaching the recommended daily allowances. Blood profile was normal for all evaluated parameters. Physical performance capacity was rather weak for strength‐oriented tasks while a normal cardiorespiratory endurance capacity was measured. Our results indicate that a vegetarian diet is not automatically a healthy diet. Proper food choices need to be made to assure the completeness and to avoid excesses or deficiencies in the diet.

Abstract

Purpose

This study aims at determining the risk of physical inactivity and sedentary behaviors on overweight and obesity among primary school children aged 10–13 years in Tanzania.

Design/methodology/approach

A case-control study was conducted from January to March 2020 involving 69 overweight/obese children as cases and 138 normal weight children as controls. Cases were identified as having body mass index-for-age ≥ +1 standard deviation (SD) and controls as those having BMI-for-age range between −2 SD to <+1 SD. A validated questionnaire was used for data collection on daily physical activities and sedentary behavior types, frequency duration and activity score. An independent sample t-test was used to compare means of activity score between cases and controls. Binary logistic regression was used to predict risk factors for overweight/obesity.

Findings

Risk factors for overweight/obesity were listening to music and/or radio for >2 h/week (OR 2.7, 95% CI 1.2–6.1) and walking for exercise <2 h/week (OR 2.1, 95% confidence interval [CI] 1.1–4.1). On the other hand, rope skipping for >2 h/week (OR 0.14, 95% CI 0.03–0.7) was a protective factor against overweight/obesity. Controls had a significantly higher mean score of being active during lunch breaks compared to cases (p = 0.012). Cases had higher weight, height and percentage body fat than controls (p < 0.001). The home environment provided more avenues for physical activity than the school environment.

Originality/value

To the best of the authors’ knowledge, this is original research work and the first case-control study to predict physical activity and sedentary behaviors as risk factors for overweight and obesity in Tanzanian school children.

Abstract

Purpose

The study aims to design metabolic syndrome (MetS) ingredient mix with optimum amino acid makeup using key foods with reported functional properties and study the efficacy of this mix to alleviate the symptoms of MetS among adult men and women with MetS.

Design/methodology/approach

In total, 25 MetS-specific ingredient mixes that included wheat flour, common legumes, fenugreek and flaxseeds were formulated by correcting their amino acid score. The suitability of these mixes was tested for the preparation of chapati (an unleavened Indian bread). Owing to its highest lysine content, the ingredient mix of whole wheat flour, oat flour, soybean, flaxseeds and fenugreek seeds was selected for the 12-week supplementation trial among patients with MetS.

Findings

The sensory scores of chapatis made using nine ingredient mixes was comparable with those of chapati made from whole wheat flour (control). The test chapatis had a significantly (p = 0.05) higher protein, ash, fibre and fat content, and lysine was also higher (591-1,006 mg/100 g) than the control chapatis (314 mg). Positive and significant changes in the anthropometry, body composition, fasting blood glucose levels, blood pressure and lipid profile of the patients with MS was seen after consumption of the selected ingredient mix.

Originality/value

Keeping in view the traditional vegetarian Indian meals which usually take care of including foods from different sources to improve their protein quality, the concern for providing protein quality to prevent metabolic abnormalities is significant for a large lacto-vegetarian population in India which depends on plant foods for obtaining essential amino acids. Obtaining optimum protein quality from meals along with maintaining a physically active lifestyle may help people have the appropriate fat to lean mass proportion which may have a protective role against MetS.

Abstract

Purpose

There is unprecedented interest by consumers to improve health and wellness through dietary means. This first study conducted in Trinidad, West Indies, aims to examine the exercise enthusiasts’ perceptions, choices, reasons and beliefs of functional foods.

Design/methodology/approach

A structured questionnaire was administered to 120 randomly chosen exercise/fitness enthusiasts at six gyms located in East and Central regions.

Findings

Only 50.5 per cent had heard of at least one term either “functional” or “nutraceutical” or “designer” foods with the most familiar term (34.3 per cent; p<0.05) being “functional”. Frequency of exercise (p<0.01) and age (p<0.05) were influential factors affecting familiarity to functional term. Tomatoes (89.5 per cent) and cabbages (83.2 per cent) were popular vegetable choices. Energy giving was selected as most (71.6 per cent; p<0.05) important health claim. The perceived benefit of functional foods was more for performance enhancement rather than for health. Functional foods were considered expensive (47.4 per cent), prevented disease (46.3 per cent), necessary for older people (37.9 per cent) and were different from others. On comparing the respondent's agreement of manufacturer's health claims of functional foods with their own beliefs, 39.0 per cent “agreed/strongly agreed” that the manufacturers exaggerated their health claims. Gender did not (p>0.05) influence responses.

Originality/value

Although, limited in sample size, the reasons given for consumption of functional foods and the chosen foods could guide marketers and food product developers. The study highlighted the need for public education on the health benefits and regulatory measures on functional foods.

– The purpose of this paper is to evaluate the effectiveness of measures designed to increase physical activity in women in secure psychiatric care.

Abstract

Purpose

The purpose of this paper is to evaluate the effectiveness of measures designed to increase physical activity in women in secure psychiatric care.

Design/methodology/approach

A range of interventions (environmental and motivational) designed to increase participation in physical activities were introduced on two secure wards for women. A pre-post design assessed frequency, duration and intensity of physical activity, attendance at physical activity sessions, exercise motivation, exercise-related mood, attitudes to exercise and health and biological indices. Measures collected over a three-month baseline period were repeated six months post-intervention.

Findings

Significant changes occurred in both attitudes to exercise and health, exercise motivation and exercise behaviour following change initiatives. With the exception of resting pulse rate and perceived exertion, the increased level of activity was not reflected in changes in body mass index, body fat or body muscle.

Practical implications

Management led, multi-disciplinary interventions to increase physical activity can have a positive impact on both lifestyle behaviours and physical health.

Originality/value

This study adds to a small literature on increasing physical activity in women in secure psychiatric settings where obstacles to change are formidable.
