ABSTRACT
Plant fats are low in saturated fats but high in unsaturated fats compared to animal fats, and are supposedly less obesogenic. This study compared the obesogenic effects of plant and animal derived fatty diets in Wistar rats. Rats of each gender were divided into three dietary (standard chow (SC), high fat diet rich in animal fat (HFDaf) and a high fat diet rich in plant fat (HFDpf)) groups of ten each and fed for 17 weeks. Anthropometric, Adiposity and nutritive variables were assessed using standard methods. Comparing HFDpf to HFDaf: Abdominal circumference (AC),initial feed intaken (IFI), final feed intake(FFI), final body weight (FBW), white adipose tissue (WAT) were increased but brown adipose tissue (BAT) decreased in male rats fed with HFDpf; also, there were increased body length, IFI, FFI but decreased AC, FBW, BAT in female rats fed with HFDpf. Comparing male to female rats: Thoracic circumference, IFI, FFI, energy intake were increased while Adiposity index decreased across diet groups in male rats; the AC, FBW increased while WAT, BAT decreased in HFDpf fed group, also, BAT was increased but AC, FBW decreased in HFDaf fed group in male rats. Palatability and high feed efficiency of consumed diets were more associated with obesogenic risk than just the level of saturation. Therefore, Obesogenic effects of fatty diets in both genders is more dependent on the quantity (amount) of fatty diet consumed than the dietary fat composition alone.
ABSTRACT
BACKGROUND: The epidemiology of lower urinary tract symptoms in adult men in Nigeria is presently not well known. AIM: To evaluate a screened population of men for lower urinary tract symptoms and their impact on the participants' quality of life. METHODS: A cohort study was conducted among men aged 40 years and older from 3 selected centres in Ibadan, Southwestern Nigeria. The presence of lower urinary tract symptoms and their impact was determined using the International Prostate Symptom Score (IPSS) administered via standardized questionnaires. RESULTS: Six hundred and fifty-five men participated in the study. The median age was 56 years with a range of 40 - 92 years. Eight percent (8%) of respondents were asymptomatic, whilst 66%, 20% and 6% had mild, moderate and severe symptoms respectively. Nocturia was the most common symptom and the second most troublesome. Overall storage (irritative) symptoms occurred with the similar frequency to voiding (obstructive) symptoms (91% v 92%), but voiding symptoms were more likely to be severe and thus more troublesome (p = <0.000.1). The severity of the individual symptoms as well as the overall score also increased significantly with age [p = 0.001]. There was a high correlation between IPSS and Quality of Life (QoL) scores (correlation coefficient 'r' = 0.75 [p = <0.0001]. Despite this, 72% of QoL respondents were satisfied with their quality of life. CONCLUSION: The frequency of non-troublesome lower urinary tract symptoms was high in adult men in this cohort of men in Southwestern Nigeria and that severity was age-related. In addition, whilst storage and voiding symptoms occurred with similar frequency, voiding symptoms were the more severe and troublesome.
ABSTRACT
BACKGROUND: Carcinoma of the prostate is now the most commonly diagnosed male cancer worldwide. However, knowledge and perception of Nigerian men about the disease has not been fully investigated. AIM: To determine the level of awareness about prostate cancer among men 40 years and older in Ibadan, Southwestern Nigeria. METHOD: Four focus group discussions were used to obtain information from 29 randomly- selected Nigerian men, aged 40 years and above, about their knowledge of the common causes of morbidity and mortality among men of their age group as well as prostatic diseases and their perceived causes. In-depth interviews were then conducted among 656 participants using questionnaires. RESULTS: Generally, the respondents and discussants were unaware of the prostate gland and its diseases; whilst relatively few knew about carcinoma of the prostate and most were ignorant of the symptoms of the disease. Among discussants and respondents who knew about the gland, most thought that benign and malignant prostatic diseases were long-term complications of promiscuity and sexually transmitted infections. All the participants were interested in receiving information about all aspects of carcinoma of the prostate. CONCLUSION: . These results indicate that a large proportion of adult Nigerian men are ignorant of the prostate gland and its diseases in general, and carcinoma of the prostate in particular. There is therefore the need for community awareness programs on prostatic diseases in our locality.
