    Anthropometric measurements and food consumption analysis of older people according to place of residence and gender: A cross-sectional study
    (Elsevier, 2021) Barcın Güzeldere, Hatice Kübra; Aksoy, Meral
    Background & aims: The older population across the world is rapidly increasing, raising the importance of a healthy and independent aging process and the factors affecting it. This study aimed to examine the food consumption habits and anthropometric measurements of older people according to their gender and the place of residence. Methods: A total of 121 healthy participants aged over 80 years who lived in rural (n:70) and urban (n:51) areas in the Aegean Region of Turkey were included in the study. A questionnaire was administered to determine the demographic data and nutritional status of the participants. Three-day food consumption was recorded and then analyzed using BeBiS 8.1. The participants' adherence to the Mediterranean diet and their Healthy Eating Index-2015 values were calculated based on their food consumption. The circumferences of the waist, hip, upper-mid arm and calf of the participants were measured by the researcher using an inelastic measuring tape. Weight, fat, muscle, water and basal metabolic rate were measured using the TANITA BC730 body impedance analyzer. Results: The mean weight, body mass index, circumferences of waist, hip and upper-mid arm,fat-free mass and basal metabolic rate were higher in the rural men than the urban ones (p < 0.05). The urban women had a higher waist-to-hip ratio than the rural ones (p < 0.05). There were no significant differences in the participants' adherence to the Mediterranean diet and their Healthy Eating Index values according to gender or the region they lived in. Nutrient intake was compared with the daily recommendations in the Turkish Nutrition Guide. It was found that the urban men consumed more carbohydrates, fats, vitamins A and C, and sodium. In contrast, energy, protein, fiber, vitamins E, D, B-1, B-2, B-6 and B-12, folic acid, magnesium, calcium, iron and zinc were consumed at lower amounts than recommendations. On the other hand, the rural men consumed more carbohydrates, fats, vitamins A, C and B-2, folic acid, sodium and zinc. Similarly, the urban and rural women were found to have a higher intake of carbohydrates, fats, vitamins A and B-2 and sodium and lower intake of other nutrients than recommendations. Conclusion: Old age is one of the most sensitive periods in a person's life cycle. Place of residence during this period may physiologically affect food intake, physical activity, and therefore, anthropometric measurements. Healthcare providers should take into account that place of residence may alter older individuals' nutritional status and anthropometric measurements.

    Association between the anthropometric measurements and dietary habits on telomere shortening in healthy older adults: A-cross-sectional study
    (Wiley, 2023) Barçın Güzeldere, Hatice Kübra; Aksoy, Meral; Demircan, Turan; Yavuz, Mervenur; Beler, Mahmut
    Aim: This study aimed to evaluate the effect of anthropometric measurements and dietary habits on telomere length in healthy older residents in rural and urban areas. Methods: This was a cross-sectional study. The study population included 81 healthy older individuals aged >= 80 years. A quantitative food frequency questionnaire was used to determine dietary habits. Anthropometric measurements were taken by researchers. The telomere length of individuals was determined from leukocytes using quantitative polymerase chain reaction. Results: Urban women had longer telomeres than rural women (P < 0.05). Rural men had significantly higher hip circumference, middle-upper arm circumference and fat-free mass than urban men (P < 0.05). It was shown that while fresh vegetable consumption was higher in rural areas, carbonated drink consumption was higher in urban areas (P < 0.05). In women, homemade bread and sugar consumption were higher in rural areas, and honey consumption was higher in urban (P < 0.05). Red meat, milk-based dessert and pastry consumption explain telomere shortening by 22.5%, 24.8% and 17.9%, respectively. In addition, the model based on anthropometric measurements also contributes to explaining telomere shortening by 42.9%. Conclusion: Red meat, milk-based dessert and pastry consumption, and waist circumference, hip circumference, waist-to-hip ratio and waist-to-height ratio are associated with telomere length. Longer telomeres are associated with a healthy, balanced, adequate diet and maintaining a healthy body weight/proportion, and they are crucial for achieving healthy aging.

    Uçuş görevlilerinin rutin yaşamlarındaki değişmenin beslenme, uyku düzeni ve bazı biyokimyasal parametrelerine yansısı
    (İstanbul Medipol Üniversitesi Sağlık Bilimleri Enstitüsü, 2020) Erdem, İrem; Aksoy, Meral
    Rutin yaşamdaki değişme, vücudun sirkadyen ritmi / saatin bozulması ile ilişkili bir kavramdır. Sirkadyen saat, insan sağlığı için önemli olan 24 saate yakın çeşitli biyolojik ritimlerden sorumludur. Günümüzde sirkadyen ritmin değişmesi ile yiyecek tüketimi ve uyku düzeni arasında bir ilişkinin ve/veya değişiminin saptanması önem taşımaktadır. Bu araştırma; uçuş görevlilerinin sirkadyen ritminin değişmesiyle ortaya çıkan farklılıkları saptamak amacıyla yapılmıştır. Araştırma Kasım 2018- Mart 2019 tarihleri arasında Türkiye'de özel bir havayolunda çalışan 29-55 yaş arası gönüllü 100 erkek uçuş görevlisi üzerinde yapılmıştır. Uçuş görevlilerinin kişisel özelliklerini, yaşam tarzı alışkanlıkları verilerini toplamak amacıyla anket formu, yiyecek tüketimlerini saptamak için yaşamlarındaki normal bir gün ve sirkadyen ritmi bozulduğunda 2 gün için alınan yiyecek tüketim kaydı, uyku kalitesini değerlendirmek için de Pittsburgh Uyku Kalitesi İndeksi (PUKİ) Ölçeği uygulanmıştır. Sirkadyen ritmin bozulmasına bağlı araştırmaya katılan uçuş görevlilerinin günlük aldıkları ortalama enerji miktarı ile bu enerjinin karbonhidrat ve yağdan gelen oranları önemli derecede artmıştır. Sirkadyen ritmi değişen uçuş görevlilerinin gece yeme eğilimleri daha fazla olmuştur. Ayrıca yetersiz uyku ve uyku kalitesinin düşük olmasına bağlı olarak biyolojik ritim bozulduğunda serotonin değerleri düşük; melatonin ve kortizol değerleri ise önemli derecede yüksek bulunmuştur (p<0,01). Sonuç olarak, yeme davranışları, yiyecek seçimi, uyku kalitesi, duygu durumlarına bağlı yeme, biyokimyasal parametreleri ve antropometrik ölçüm bulguları sirkadyen ritim değişikliğinden etkilediği saptanmıştır.
