Jeenduang N, Horpet D, Plyduang T, Nuinoon M. Association of thalassemia, hemoglobinopathies, and vitamin D levels with lipid profile in adults: Community-based research in southern Thai population. Heliyon 2024; 10:e31374. [PMID: 38813217 PMCID: PMC11133901 DOI: 10.1016/j.heliyon.2024.e31374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 05/10/2024] [Accepted: 05/15/2024] [Indexed: 05/31/2024] Open
Abstract
This study explored the frequency of lipid-lowering drug use in the thalassemia population and investigated the association of thalassemia, hemoglobinopathies, and serum 25(OH)D levels with lipid profile and red blood cell parameters. A combination of cross-sectional and community-based studies was conducted with 615 participants from the southern Thai population. Thalassemia and hemoglobinopathies were diagnosed using hemoglobin analysis and polymerase chain reaction-based methods to genotype globin genes. Biochemical parameters such as lipid profile, fasting blood sugar (FBS), and serum 25(OH)D levels were assessed using standard enzymatic methods and electrochemiluminescence immunoassays. Differences in the means of hematological and biochemical parameters between the thalassemia and non-thalassemia groups were compared and analyzed. A significantly lower frequency of lipid-lowering drug use was observed in the thalassemia group. Thalassemia, with clearly defined abnormalities in red blood cells, is associated with a 4.72-fold decreased risk of taking lipid-lowering drugs. Among thalassemia participants, the total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels were significantly lower than those in non-thalassemia participants. The prevalence of hypovitaminosis D in carriers of thalassemia and/or hemoglobinopathies in the southern Thai population was 53 % in females and 21 % in males. The highest lipid profile was observed in samples without thalassemia and hypovitaminosis D. The genetics of thalassemia and hemoglobinopathies with obviously abnormal red blood cells could explain the variable lipid levels, in addition to lipid metabolism-related genes and environmental factors. However, the effect of thalassemia on lipid levels in each population may differ according to its prevalence. A larger sample size is required to confirm this association, especially in countries with a high prevalence of thalassemia.

Pyae TW, Sanchaisuriya K, Athikamanon S, Sanchaisuriya P, Srivorakun H, Chaibunruang A, Fucharoen S. Anemia in an ethnic minority group in lower northern Thailand: A community-based study investigating the prevalence in relation to inherited hemoglobin disorders and iron deficiency. PLoS One 2023; 18:e0287527. [PMID: 37352175 PMCID: PMC10289360 DOI: 10.1371/journal.pone.0287527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 06/06/2023] [Indexed: 06/25/2023] Open
Abstract
BACKGROUND Anemia is a globally well-known major public health problem. In Southeast Asia where there is ethnic diversity, both iron deficiency (ID) and inherited hemoglobin disorders (IHDs) are prevalent and are considered to be the major factors contributing to anemia. However, little is known about the anemia burden among the ethnic minorities. In this study, we determine the burden of anemia, in relation to ID and IHDs, among the Karen ethnic minorities living in the rural area of lower northern Thailand. METHODS A cross-sectional community-based study was conducted at Ban Rai district, Uthai Thani province. Study participants included 337 Karen people aged over 18 years. Socio-economic and health-related information were obtained through interviews and recorded by local health staff. Anemia, IHDs and ID were diagnosed according to standard laboratory methods. Multivariate logistic regression analysis was applied to identify risk factors of moderate-to-severe anemia. RESULTS The prevalence of overall anemia was 27.9% (95% CI = 23.2-33.0). Mild and moderate anemia were detected in 18.7% (95% CI = 14.7-23.3) and 8.9% (95% CI = 6.1-12.5) respectively. Severe anemia was found in one case (0.3%). Various forms of IHDs were identified in 166 participants, constituting 49.3% (95% CI = 43.8-54.7). The most common form of IHDs was α+-thalassemia (32.9%), followed by β-thalassemia (12.2%), α0-thalassemia (4.2%), hemoglobin E (3.9%), and hemoglobin Constant Spring (0.9%). Among 308 participants who were investigated for ID, the prevalence was discovered to be 6.8% (95% CI = 4.3-10.2). Analysis of risk factors of moderate-to-severe anemia revealed that individuals with ID, β-thalassemia and age > 65 years were at high risk with adjusted odds ratio of 17 (95% CI = 3.8-75.2), 6.2 (95% CI = 1.4-27.8) and 8.1 (95% CI = 1.6-40.4) respectively. CONCLUSIONS Anemia among the Karen is of public health significance; and IHDs are the major contributing factors. Because of the high risk of developing moderate-to-severe anemia, special attention should be paid to individuals affected with ID, β-thalassemia and the elderly. Public awareness of the health burden of severe thalassemia syndromes should also be campaigned.

Anemia, iron deficiency, and thalassemia among the Thai population inhabiting at the Thailand-Lao PDR-Cambodia triangle. Sci Rep 2022; 12:18643. [PMID: 36333424 PMCID: PMC9636127 DOI: 10.1038/s41598-022-22016-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 10/07/2022] [Indexed: 11/06/2022] Open
Abstract
Anemia is a major public health problem in many areas of Southeast Asia. Ascertaining anemia and defining its underlying causes is essential for providing appropriate care, management, and establishment of a control program. Limited studies on these have been carried out on people living at the borders of Thailand, Lao PDR, and Cambodia. This cross-sectional study was done in four areas along the borders of Thailand, Lao PDR, and Cambodia. Blood specimens were collected from subjects aged 15-18 years in four districts including Kantharalak, Si Sa Ket province (n = 36), Nam Khun (n = 109), Nam Yuen (n = 98), and Na Chaluai (n = 128), Ubon Ratchathani province, Thailand. RBC parameters were recorded, and serum ferritin (SF) level was measured. Diagnosis of thalassemia and hemoglobinopathies was based on hemoglobin (Hb) and DNA analyses. Measurement of C-reactive protein was performed to exclude false-negative result of iron deficiency. The prevalence of anemia was found to be 25.1%. ID accounted for only 10.5%. Various types of thalassemia were identified in 67.7% of the subjects. The overall prevalence of thalassemia included 3.5% α0-thalassemia, 0.8% β-thalassemia, 47.7% Hb E, and 53.6% α+-thalassemia. The proportions of ID, thalassemia and combined ID and thalassemia among anemic subjects were 6.5%, 66.6%, and 20.4%, respectively. The results indicate that thalassemia and hemoglobinopathies rather than ID are major causes of anemia in Thailand-Lao PDR-Cambodia triangle. This information should prove useful for implementing an anemia control program in the regions.

Abstract
Anemia is a global health problem. This paper reviews literature on the prevalence of anemia in Sri Lanka. We searched EBSCO (Elton Bryson Stephens Company), Cochrane Library, and Medline for articles on prevalence and molecular basis of anemia in Sri Lanka from January 2000 to May 2021. Forty articles were selected. Most of the studies were on prevalence of anemia among children and pregnant women. All the studies had restricted themselves to assess the contributing factors for anemia in limited age categories. Most articles had attempted to determine the overall prevalence of anemia and the contribution of iron deficiency to it. There were only a few studies on prevalence and molecular basis of hemoglobinopathies and even fewer on the prevalence of anemia of chronic disease. None of the studies had attempted to assess the national prevalence of red cell membranopathies and enzymopathies. The published data on prevalence of anemia in Sri Lanka are incomplete. This review emphasizes the value of a much broader survey on anemia covering all age categories including the elderly and conducting a national survey including anemia of chronic disease and on red cell membranopathies and enzymopathies in Sri Lanka.

Abstract
Introduction: Anemia is a common blood disorder in the elderly which is associated with numerous poor medical outcomes. However, there is currently no study that assesses anemia prevalence of the Indonesian elderly population aged ≥60 years old in multiple provinces and analyzes its association with handgrip muscle strength using a large sample size. Aim: We aimed to elucidate the prevalence of anemia and analyze factors associated with handgrip strength in elderly. Method: This was a cross-sectional study using data from the Indonesian Family Life Survey-5 (IFLS-5). All participants aged ≥60 years old were included in this study. Exclusion criteria were: (1) respondents who refused to take health measurements (hemoglobin (Hb) level, handgrip strength, weight, stature, and waist circumference); (2) respondents with incomplete or missing data; (3) respondents with history of stroke; and (4) respondents with history of pain, swelling, inflammation, injury, and surgery on one or both hands within the last 6 months. The dependent variable for this study was handgrip strength. Subjects were classified as weak if the handgrip strength was <28 kg for men and <18 kg for women based on classification from the Asian Working Group for Sarcopenia (AWGS) 2019. The independent variables were Hb level, gender, age, body mass index (BMI), waist circumference, smoking history, comorbidities, and current use of drug therapies. Based on WHO standard, male and female participants with Hb less than 13 g/dL and 12 g/dL, respectively, are defined as anemic. Statistical analyses used included correlation, bivariate logistic regression, and multivariate logistic regression. Result: A total of 3192 individuals were selected for analysis. Overall, 38.8% of participants had anemia, and the prevalence of anemia increases with age. A total of 56.30% of participants aged ≥80 years had anemia. There was a positive correlation between Hb level and handgrip strength in the Indonesian elderly population (r: 0.349; p value: <0.001). Multivariate analysis showed that anemia was significantly associated with weak handgrip strength (OR: 1.557; 95% CI: 1.314-1.846; p value: <0.001). Age ≥ 80 years (OR: 5.234), age 70-79 years (OR: 3.152), low BMI (OR: 1.827), and hypertension (OR: 1.340) were associated with weak handgrip strength in multivariate analysis. Conclusion: The prevalence of anemia in the Indonesian elderly was 38.8% and anemia was associated with weak handgrip strength. The association of anemia with weak handgrip strength is more pronounced in males and the elderly aged ≥80 years.

Anemia 2021; 2021:9523836. [PMID: 33728063 PMCID: PMC7935608 DOI: 10.1155/2021/9523836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 08/12/2020] [Accepted: 02/19/2021] [Indexed: 12/03/2022] Open
Abstract
INTRODUCTION Anaemia is a common problem in sub-Saharan Africa. While most literature has focused on children, women of childbearing age, and pregnant women, data for the elderly population are relatively scarce. Anaemia exhorts negative consequences to functional ability of elderly patients, both physically and cognitively. The purpose of this study was to determine the prevalence of anaemia, severity, and micronutrient deficiency status in the elderly hospitalized patients in Tanzania. METHODS A total of 156 hospitalized adults aged 60 years and above were enrolled in this study. A structured questionnaire was used to capture sociodemographic and clinical characteristics. Blood samples were collected, and a complete blood count, serum cobalamin, serum ferritin, and serum folate levels were measured to assess anaemia and micronutrient deficiency status in all participants who had anaemia. RESULTS The prevalence of anaemia was 79.5% (124/156) with severe anaemia in 33.9% (42/124) of participants, moderate anaemia in 42.7% (53/124) of participants, and 23.4% (29/124) of all participants had mild anaemia. Micronutrient deficiency was found in 14.5% (18/124) of all participants with anaemia. Combined deficiency (either iron and vitamin B12 deficiency or iron and folate deficiency) was the most common micronutrient deficiency anaemia with a frequency of 33.3% (6/18), followed by isolated iron and folate deficiencies at equal frequency of 27.8% (5/18) and vitamin B12 deficiency at 11.1% (2/18). CONCLUSION The prevalence of anaemia in the hospitalized elderly population is high warranting public health attention and mostly present in moderate and severe forms. Micro-nutrient deficiency anaemia is common in this age group and is mostly due to combined micronutrient deficiency.

Abstract
OBJECTIVES The prevalence of anemia and its impact on frailty and physical function amongst the multiethnic older populations in the Southeast Asian (SEA) countries are often not well studied. Singapore, a nation comprised of multiethnic communities, is one of the most rapidly aging population globally. We aim to evaluate the prevalence of anemia and its impact on frailty, and physical function in Healthy Older People Everyday (HOPE)- an epidemiologic population-based study on community-dwelling older adults in Singapore. DESIGN Cross-sectional study. SETTING Community. PARTICIPANTS 480 adults ≥ 65 years old. MEASUREMENTS Data were collected from interviewers-administered questionnaires on socio-demographics, FRAIL scale, Mini-Mental State Examination, EQ-5D, Barthel Index, and Lawton index. Hemoglobin concentration and physical assessments, including anthropometry, grip strength, timed up-and-go (TUG) were measured. RESULTS The overall prevalence of anemia was 15.2% (73 out of 480). The Indian ethnic group had the highest prevalence of anemia (32%, OR=3.02; 95%CI= 1.23-7.41) with the lowest hemoglobin concentration compared to the overall population (13.0±1.3g/L and 13.5±1.4g/L, p=0.02). Hemoglobin levels and anemia were significantly associated with frailty (OR=2.28; 95% CI=1.02-5.10), low grip strength (OR=1.79; 95% CI=1.01-3.03), ≥ one IADL impairment (OR=2.35; 95% CI=1.39-3.97). Each 1 g/dL increase in hemoglobin was associated with a 6% decrease in frailty odds after adjusting for potential covariates (OR = 0.94, 95% CI: 0.90-0.99). There was a significant difference in the mean TUG between the non-anemic (11.0±3.4 seconds) and anemic (12.3±6.0 seconds, p=0.01) counterparts, but no difference in the number of falls. CONCLUSION In our multiethnic Asian population, anemia was adversely associated with frailty, decreased muscle strength, and IADL impairment. Health policies on anemia screening should be employed to avoid or potentially delay or reverse these adverse outcomes associated with anemia. Recognition, evaluation, and treatment of anemia amongst this vulnerable population is warranted.

Abstract
Anemia affects a substantial fraction of the elderly population, representing a public health problem that is predicted to further increase in coming years because of the demographic drive. Being typically mild, it is falsely perceived as a minor problem, particularly in the elderly with multimorbidity, so that it often remains unrecognized and untreated. Indeed, mounting evidence indicates that anemia in the elderly (AE) is independently associated with disability and other major negative outcomes, including mortality. AE is generally multifactorial, but initial studies suggested that etiology remains unexplained in near one-third of cases. This proportion is consistently declining due to recent advances highlighting the role of several conditions including clonal hematopoiesis, "inflammaging," correctable androgen deficiency in men, and under-recognized iron deficiency. Starting from a real-world case vignette illustrating a paradigmatic example of anemia in an elderly patient with multimorbidity, we review the main clinical and pathophysiological aspect of AE, giving some practical insights into how to manage similar cases.
