Association between the dietary inflammatory index and disability in Japanese older people.

OBJECTIVES: To examine the demographic and lifestyle characteristics related to the dietary inflammatory index (DII™) score and to evaluate the association between DII score and disability among older people in Japan. DESIGN: Cross-sectional design. The DII score was calculated from nutrient intake information obtained from a FFQ. Disability was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence questionnaire. Overall disability and disability in each component of everyday competence, that is, instrumental activities of daily living (IADL), intellectual activities and social participation, were assessed. Those with a deficit in one or more activities were defined as disabled. SETTING: Five non-urban areas in Japan. PARTICIPANTS: A total of 1642 Japanese older people aged 65 years or older. RESULTS: Women, residents of Oga-shi, and those with a higher education and greater frequency of shopping followed a more anti-inflammatory diet, while those living alone and residents of Minamiawaji-shi had higher dietary inflammation. A pro-inflammatory diet was associated with higher odds of overall disability and disability in each component of competence: overall disability, OR (95 % CI) = 1·26 (1·16, 1·36); IADL disability, OR (95 % CI) = 1·16 (1·07, 1·26); disability in intellectual activities, OR (95 % CI): 1·30 (1·20, 1·40); and disability in social participation, OR (95 % CI) = 1·20 (1·11, 1·29). CONCLUSIONS: Sex, living alone, education, frequency of shopping and area of residence were shown to be determinants of DII score in Japanese older people. DII score was positively associated with disability.

Significant effects of Fatwa-based perception on contraceptive practice among Muslim women in south Jordan under the early stage of fertility transition.

An interview survey of 450 Muslim women in a rural village of south Jordan under the early stage of fertility transition was conducted to explore major causes of contraceptive use, taking both their sociodemographic attributes and fatwa (Islamic jurisprudence)-based perception into account. Discriminant analysis, which was performed for the subject women divided into 15- to 29-, 30- to 39-, and 40- to 49-year age groups, revealed that "the number of living children" in the former and "to do contraception for good care of children" in the latter played significant roles in discrimination into contraceptive user and nonuser groups for any age groups. To cope with demographically and socioeconmically vulnerable situations, contraceptive prevalence rate should be increased by means of government-led family planning programs in cooperation with the imam (Muslim religious leaders and priests) through fatwa, in which special attention is paid to traditional norms, represented by good childcare.

Long-lasting effects of sedentarization-induced increase of fertility on labor force proportion in an Arab socieity: a case study in south Jordan.

Based on the authors' genealogical-demographic data of a Bedouin-origin clan in south Jordan which settled down in 1948, this paper aimed to report the long-lasting effects of increase in fertility induced by sedentarization on the labor force proportion, defined as percent of persons aged 15-64 years. The results highlighted that this proportion had an inverse relation with the total fertility rate and tended to fluctuate up to the present time with an interval of several decades, suggesting that a Bedouin-origin sedentarized group met alternately with the phase of high fertility and low proportion of labor force and the other phase of an opposite pattern. At present, unemployment of males, who have been engaged in subsistence and cash-earning work, was high especially in younger groups basically due to the narrow land of the clan (only 35 hectares for 456 people in 2005) for agriculture and the limited opportunities for cash-earning jobs. Taking into consideration that Bedouin-origin people sedentarized according to the government policy, it is needed for the government to support rural development plans of sedentarized Bedouin peoples.

Ineffective contraceptive use and its causes in a natural fertility population in southern Jordan.

Based on our interview survey of 574 randomly selected married women from a rural population in the South Ghor district, Jordan, where traditional Arab customs have been persistently maintained, in this paper we analyze the age-specific marital fertility rates (ASMFRs) and contraceptive practices, especially the prevalence and duration of contraceptive use. The ASMFRs fitted the natural fertility pattern proposed by Coale and Trussell's model, and the total fertility rate was estimated to be 7.2. Even though the prevalence rate of modern contraceptive methods has reached 14.3%, because of the recent increase among young women in particular, the users had larger numbers of children than the nonusers and the duration of contraceptive use was short, especially at young ages (e.g., about 90% 24-month discontinuation probabilities in 15-19- and 20-24-year-olds). These ineffective contraceptive uses were related to traditional Arab norms, represented by the pooled proportion of "as many as possible" and "up to God" answers to the ideal number of children (70% of men and 30% of women).

Effects of polygyny and consanguinity on high fertility in the rural Arab population in South Jordan.

Based on the authors' interview survey for 608 randomly selected women of the rural Arab population in the South Ghor district of Jordan, this paper examined the effects of polygyny and consanguinity on high fertility, which was recognized as natural fertility. The prevalence of polygynous and consanguineous marriages was 28.0% and 58.1%, respectively, largely reflecting the population's traditional marriage customs. The findings highlighted a significantly higher total marital fertility rate (TMFR) in the monogamous wives (10.5) than in the senior polygynous (8.1) and junior polygynous wives (8.6); the TMFR did not significantly differ among the wives of non-consanguineous, first-cousin and second-cousin marriages. The formation of polygynous marriage was decided by the husband, mostly as a result of his senior wife's infecundity or sub-fecundity, and the age of the husband at marriage to his junior polygynous wife was high in many cases, leading to a decline in this wife's fecundity.
